What happens when i. n-butyl chloride is treated with alcoholic ' KOH' ii. bromobenzene is treated with ' Mg' in the presence of dry ether, ii. chlorobenzene is subjected to hydrolysis, iv. ethyl chloride is treated with aqueous KOH, v. methyl bromide is tréated with sodium in the presence of dry ether, vi. methyl chloride is treated with KCN?

What happens when:Methyl chloride is treated with KCN.

What happens when:Bromobenzene is treated with Mg in the presence of dry ether.

An organic compound A, C₈H₆ on treatment with dilute sulphuric acid-containing mercuric sulphate gives a compound B , which can also be obtained from a reaction of benzene with an acid chloride in the presence of anhydrous aluminium chloride. The compound B, when treated with Iodine in aqueous KOH, yields C and a yellow compound D. Identify A B C and D with justification.

CH_3 Cl , sodium and dry ether b. Benzene, CH_3 Cl and AlCl_3 i. Name the products formed in each case. ii. Name the reactions.

A mixture of tert - Butyl chloride and Ethyl chloride is treated with sodium in ether medium.
