Answers

The bond order for both H2+ and H2− is the same but H2+ is more stable than H2− due to the absence of electrons in the anti-bonding orbital.

Electrons that spend most of their time between the nuclei of two atoms are placed into the bonding orbitals, and electrons that spend most of their time outside the nuclei of two atoms are placed into antibonding orbitals.

In chemical bonding theory, an antibonding orbital is a type of molecular orbital that weakens the chemical bond between two atoms and helps to raise the energy of the molecule relative to the separated atoms. Such an orbital has one or more nodes in the bonding region between the nuclei.

Furthermore, the bonding electron is the electrons that stick together and fall in the lowest state. While anti-bonding electron is unbounded or free electrons that move to the higher orbital state.

Ethane can be dehydrogenated to ethylene, which is often used as a raw material for polymer manufacturing.

The process of dehydrogenation involves removing hydrogen from an organic substance to create a new chemical (e.g., to convert saturated into unsaturated compounds).

Answers

The reaction of benzene with an alkyl chloride and aluminum trichloride is called a Friedel-Crafts alkylation.

What is chloromethane and aluminum trichloride?The aluminum trichloride is a Lewis acid that reacts with the alkyl chloride, and this converts the alkyl group into a very good electrophile. The overall reaction is an electrophilic aromatic substitution. A pi bond of the benzene ring will attack the electrophile as a nucleophile and form a new carbon-carbon bond. The result is a monosubstituted isopropyl group on the benzene ring.However, we are told that the conditions are set up to encourage dialkylation. The isopropyl group is a group that donates electron density through induction.
Therefore, it is an ortho- and para-directing group. This means that once one isopropyl group is substituted on to the benzene ring, the second substitution will be favoured in the ortho- and para-positions. In this instance, the major product is the 1,4-disubstituted product. The reason being is that the isopropyl groups are very bulky, and the steric hindrance of having two isopropyl groups adjacent leads to a small amount of this product being formed.

2CO2(g)+12H+(aq)+12Cu+(aq)= C2H5OH(l)+3H2O(l)+12CU2+(aq)
reduction
oxidation

Answers

The redox reaction is as follows:

2CO2(g) + 12H+(aq) + 12Cu+(aq)

Cu2+(aq)

Balance the charge by adding electrons as follows:

Cu+(aq) ⇒ Cu2+(aq) + 1e- Balanced oxidation half-reaction.

A redox reaction is a redox chemical reaction in which the oxidation state of the reactants changes. The term redox stands for reduction-oxidation. All redox reactions can be divided into two distinct processes: reduction and oxidation processes.

Redox reactions are reactions in which both oxidation and reduction occur. A substitution reaction is an example of a redox reaction in which one species is oxidized and the other is reduced. A redox reaction is a type of chemical reaction in which electrons are transferred between two species.
