What is alpha hydrogen in a carbonyl compound?The first carbon atom linked to a functional group, such as a carbonyl, is the alpha carbon. Through a resonance stabilization process, the carbonyl group mildly acidifies the alpha hydrogen (the hydrogen on the alpha carbon).Because the functional group here is carbonyl and the alpha carbon to this is the carbon connected to the benzene ring is carbonyl, there is no alpha hydrogen in benzaldehyde.As seen in the table below, the acidity of alpha hydrogens varies per carbonyl functional group.

Answer:

Reactions at the α-Carbon

Many aldehydes and ketones undergo substitution reactions at an alpha carbon, as shown in the following diagram (alpha-carbon atoms are colored blue).

Explanation:

These reactions are acid or base catalyzed, but in the case of halogenation the reaction generates an acid as one of the products, and is therefore autocatalytic. If the alpha-carbon is a chiral center, as in the second example, the products of halogenation and isotopic exchange are racemic. Indeed, treatment of this ketone reactant with acid or base alone serves to racemize it. Not all carbonyl compounds exhibit these characteristics, the third ketone being an example.

Two important conclusions may be drawn from these examples. First, these substitutions are limited to carbon atoms alpha to the carbonyl group. Cyclohexanone (the first ketone) has two alpha-carbons and four potential substitutions (the alpha-hydrogens). Depending on the reaction conditions, one or all four of these hydrogens may be substituted, but none of the remaining six hydrogens on the ring react. The second ketone confirms this fact, only the alpha-carbon undergoing substitution, despite the presence of many other sites. Second, the substitutions are limited to hydrogen atoms. This is demonstrated convincingly by the third ketone, which is structurally similar to the second but has no alpha-hydrogen.

Of all the elements, it has the lowest melting and boiling points. In the observable universe, it is the second-lightest and second-most abundant element (hydrogen is the lightest and most abundant). More than 12 times the mass of all the heavier elements put together, it makes up around 24% of the total mass of the elements.

Due to the highest high nuclear binding energy (per nucleon) of helium-4 compared to the following three elements after helium, its abundance is comparable to this in both the Sun and Jupiter. The fact that helium-4 is a byproduct of both nuclear fusion and radioactive decay is further explained by its high binding energy.

Answers

Ethane is the limiting reactant, so no mass of ethane will be left over by the chemical reaction. All the mass will react, the 8.1 grams of ethane.

How much grams of ethane will react, explain.

First of all, we need to determine the reaction and the limiting reactant to work with the stoichiometry.

The equation is: 2C₂H₆ + 7O₂ →  4CO₂ + 6H₂O

We define the moles of the reactants:

8.12 g / 30 g/mol = 0.270 moles of ethane

13g / 32 g/mol = 0.406 moles of oxygen

To determine the limiting reactant, we start with oxygen:

7 moles of O₂ can react with 2 moles of ethane

Then, 0.406 moles of O₂ will react with (0.406 . 2) / 7= 0.116 moles of ethane.

We do not have enough ethane, just only 0.07 moles to react.

why are all of the elements in group 18 relatively unreactive whereas those in group 17 are reactive

Answers

Because they only require one electron to form an octet

What is octet?

The existence of 8 electrons in an atom's outermost shell indicates that the atom is stable and has the electron configuration of an inert gas.

Every atom wants to be stable, therefore they combine with one another to reach the octet state by gaining, losing, or sharing electrons.

According to the electronic theory of chemical bond formation, atoms can unite by passing, that is, gaining or losing valence shell electrons from one element or atom to another, or by dividing or sharing them to achieve a complete octet in their final shells. The octet rule is what it's called.

The rule of eight, electronic theory of valence, and octet theory of valence are all names for the octet rule. According to the octet theory:

Atoms interact with one other by losing, gaining, or sharing electrons during the creation of a chemical bond. They do, however, develop a stable outermost shell of eight electrons.

Elements in Group 18 have complete outer energy levels and do not easily form ions. Because they only require one electron to create an octet, Group 17 elements are highly reactive.

Answers

N₂ has a bond order of three. O₂ has a bond order of two. this means that N₂ is more stable than O₂ and N₂ has a shorter bond length than O₂

The bond order is the number of bond pairs of electrons between two atoms. For covalent bonds between two atoms, a single bond has a bond degree of 1, a double bond has a bond degree of 2, a triple bond has a bond degree of 3, and so on.

Bond order is described as the gap among the facilities of covalently bonded atoms. The bond duration is decided via way of means of the wide variety of electrons within side the bond (bond order). The higher the bond order, the stronger the attraction between the two atoms and the shorter the bond length. In general, the length of a bond between two atoms is approximately the sum of the covalent bond radii of the two atoms. Bond lengths are expressed in picometers. Therefore, the bond lengths increase in the order:

Single bond > double bond > Triple bond

The higher the bond order, the more stable the molecule. A stable bond is less likely to break and therefore has a higher binding energy. As the bond order increases, the bond length decreases. Triple bonds are more energetic and stable because they have shorter bond lengths than double or single bonds

Therefore, N₂ has a bond order of three. O₂ has a bond order of two. this means that N₂ is more stable than O₂ and N₂ has a shorter bond length than O₂

Shale oil is similar to petroleum, and can be refined into many different substances, including diesel fuel, gasoline, and liquid petroleum gas (LPG).The difference between shale oil and crude oil comes down to how it is extracted. Because shale oil is bound up tightly in impermeable rock, it is considered tight oil and requires hydraulic fracturing to be extracted. Crude oil can be drilled out conventionally.Shale oil is a substitute for conventional crude oil; however, extracting shale oil is costlier than the production of conventional crude oil both financially and in terms of its environmental impact.Russia has the biggest shale oil reserves in the world. But in terms of shale gas reserves, America is not the biggest shale oil reserve holder.

How fast is Brandon driving?The speed of a body is the distance it travels per unit of time. That means that we can also find out how far anobject moves in a certain amount of time if we know its speed: we use the equation "distance = speed time."Here, we don't know either Brandon's speed or Shanice's, but since the question asks for Brandon's speed, that's what we'll use as our variable x.The distance Shanice covers in miles is 93, and the time in hours is 1.5. Her speed is 10 less than twice Brandon's speed.Shanice's speed is:x - 10 miles per hour.Substituting into the equation distance = speed time gives us93 = ( x - 10)1.5First we distribute, to get93 = 3x -Then we add 15 to both sides to get108 = 3x.Finally we divide by 3 to get= x.Brandon is driving at miles per hour.Check: We can check this answer by considering the situation another way: we can solve for Shanice's speed instead of Brandon's and then check that against Brandon's speed.The equation for Shanice's speed is simply 2x - 10 = 2(-1072 - 10 = 62So, Shanice is traveling atmiles per hour.The problem tells us that Shanice is traveling 10 mph slower than twice Brandon's speed;that would mean that 62 is equal to 2 times 36 minus 10. Is that true? Well, 2 times 36 is 72, minus 10 is 62. murray mixes 2 quarts of liquid A and 8 pints of liquid B to make a compound. How many gallons of compound are produced?
