Write balanced chemical equations fro the following reactions and name the reactions:

(i) Acetamide is heated with bromine and sodium hydroxide solution.

(ii) Benzaldehyde is treated with 58% and sodium hydroxide solution.

Give one chemical test to distinguish between the following pairs of compounds: 
(i) Ethylamine and diethylamine.
(ii) Acetaldehyde and benzaldehyde

An organic compound A with molecular formula C₂H₇N on reaction with nitrous acid gives a compound B. B on controlled oxidation gives compound C. C reduces Tollen’s reagent to give silver mirror and D. B reacts with D in the presence of concentrated sulphuric acid to give sweet smelling compound E. Identify A, B, C, D and E. Give the reaction of C with ammonia.

Give balanced equations for the following reactions: 
(i) Acetaldehyde is heated with hydroiodic acid in the presence of red phosphorous.
(ii) Calcium acetate is subjected to dry distillation.
(iii) Sodium ethoxide is treated with ethyl bromide.
(iv) Benzaldehyde is treated with sodium bisulphite.

An organic compound A with molecular formula C7H8 on oxidation by chromylchloride in the presence of CCl4 gives a compound B which gives positive tollen’s test. The compound B on treatment with NaOH followed by acid hydrolysis gives two products C and D. C on oxidation gives B which on further oxidation gives D. The compound D on distillation with soda lime gives a hydrocarbon E. Below 60oC, concentrated nitric acid  reacts with E in the presence of concentrated sulphuric acid forming a compound F. Identify the compounds A, B, C, D, E and F.

Give one good chemical test to distinguish between the following pairs of organic compounds:

(i) Benzaldehyde and acetone.

(ii) Methylamine and dimethylamine.

An organic compound A has the molecular formula of C₇H₆O. When A is treated with NaOH followed by acid hydrolysis, it gives two products, B and C. When B is oxidised, it given A, When A and C are each treated separately with PC1₅, they give two different organic products D and E.

(i) Identify A to E.

(ii) Give the chemical reaction A is treated with NaOH and name the reaction.
