Dipole-dipole interactions are significantly weaker than those between two ions, each of which has a charge of at least 1, or between a dipole and an ion, where at least one of the species has at least a full positive or negative charge, because each end of a dipole only has a fraction of the charge of an electron.

A hydrogen bond is an attraction between a hydrogen that is slightly positive on one molecule and a hydrogen that is slightly negative on another molecule. Both the characteristics of water and some biological entities, such proteins, depend on hydrogen bonds. Dipole-dipole interactions, which result from the close association of induced or permanent dipoles, are weak interactions. Van der Waals interactions are the name given to these forces taken as a whole. These interactions are widespread in proteins and range widely in strength. Examples of polar compounds that interact dipole-dipole include hydrogen chloride (HCl), carboxylic acids (such as acetic acid), and amino acids. A polar molecule's positive end will pull another molecule's negative end and change the other molecule's location. Polar molecules are those that have a net moment of dipole. The bond and molecule are regarded as being nonpolar if the net dipole moment is zero or extremely tiny. Chemical bonds between atoms with comparable electronegativity levels typically have very modest dipole moments.

One of several properties is heat capacity. By dividing an object's heat capacity by its mass, one can determine the corresponding intense property, known as the specific heat capacity. The molar heat capacity of a substance is obtained by dividing its heat capacity by the number of moles in the substance. Measured in terms of volumetric heat capacity, heat capacity is measured per volume.

Tertiary radicals are most stable.

The radical's energy level is referred to as its stability. The radical is unstable when its internal energy is high. It will make an effort to lessen its energy level. The radical is stable if its internal energy level is low.

The relative stability of radicals dictates their respective reactivity because the alkyl radical is a crucial intermediate in the halogenation process of alkanes. The more reactive alkane is the one that produces the more stable carbon radical.

Different alkyl radical structures exhibit various stabilities. The stability of radicals follows the same pattern as that of carbocations, with tertiary radicals being the most stable and primary and methyl radicals being the least stable.

Because alkyl groups stabilise the unpaired electron by a delocalization phenomenon known as hyperconjugation, the tertiary radical is the most stable.

Answer: 8/9

Explanation: took the quiz gang

The equivalent mass when it reacts with chlorine to form VCl₅ is 10.19883 g/mol.

Calculations are made to determine the equivalent masses of acids, bases, and salts. Acids' molecular masses are equal to their equivalent masses as bases. The molecular mass of a base and its acidity are equal in mass. Total positive valency of metal atoms divided by the salt's molecular mass gives the salt's equivalent mass.

Equivalent mass= molar mass/ valency

(a) For VCl₅, V will have a valency of +5, or more precisely, the oxidation state is +5, since chlorine exhibits a charge of -1. 5 chlorine atoms exhibit a charge of -5, and V exhibits a charge of +5.

so equivalent mass = 50.99415/5 = 10.19883 g/mol.

The pH of the solution is pH = 1.65

Final volume of the solution = 250.00 ml +  51 ml

Which on adding gives us the volume of solution as = 301 ml

Since the volume is supposed to be expressed in literes

thus the volume is 301/ 1000 = 0.301 L

Now,

[HCOO-] = 0.021 mol / 0.301 L = 0.069 M

[ HCOOH ] = 0.084 mol/ 0.301 L = 0.279 M

So the pH can be calculated by:

pH = 3.75 + log { 0.069 / 0.279 }

pH = 3.75 -  2.10

pH = 1.65
