Will there be reaction of iodine with benzene Why?

Iodine can be easily oxidized using, nitric acid. HNO3 in the presence of an acid and Iodine generates Iodine cation that reacts with Benzene giving Iodobenzene, Nitrogen dioxide, and water. As HNO3 is consumed in the reaction, hence it is a reagent and not a catalyst.

What does benzene react with?

Benzene reacts with chlorine or bromine in the presence of a catalyst, replacing one of the hydrogen atoms on the ring by a chlorine or bromine atom. The reactions happen at room temperature. The catalyst is either aluminium chloride (or aluminium bromide if you are reacting benzene with bromine) or iron.

Which catalyst is used during halogenation of benzene?

Benzene reacts with chlorine or bromine in an electrophilic substitution reaction, but only in the presence of a catalyst. The catalyst is either aluminum chloride (or aluminum bromide if you are reacting benzene with bromine) or iron.

What is halogenation of benzene?

Halogenation is an example of electrophillic aromatic substitution. In electrophilic aromatic substitutions, a benzene is attacked by an electrophile which results in substition of hydrogens.

How do you add benzene?

An alkyl group can be added to a benzene molecule by an electrophile aromatic substitution reaction called the Friedel‐Crafts alkylation reaction. One example is the addition of a methyl group to a benzene ring. The mechanism for this reaction begins with the generation of a methyl carbocation from methylbromide.

How do you add NO2 to benzene?

The nitration of benzene Nitration happens when one (or more) of the hydrogen atoms on the benzene ring is replaced by a nitro group, NO2. Benzene is treated with a mixture of concentrated nitric acid and concentrated sulfuric acid at a temperature not exceeding 50°C.

How will you convert I Ethyne to benzene?

When ethyne gas is passed through the red-hot iron tube, it leads to the formation of cyclic aromatic compound. When acetylene is heated in red-hot iron tube at 873 K, benzene is obtained. Ethyne could be directly converted into benzene in the presence of red-hot Cu or Fe.

How can you prepare benzene from lime?

Benzene can be prepared from aromatic acids through decarboxylation reaction. In this process, the sodium salt of the benzoic acid (sodium benzoate) is heated with soda lime to produce benzene along with sodium carbonate.

Which is not Sandmeyer process?

In sandmeyer’s reaction Iodo Benzene cannot be formed because of its large size.
