+
(c) RN(COCH₃ )₃Cl⁻
(d) R – CONH₂

Answer 1

Explanation:

R - NH₂ + CH₃COCl → A

(excess)

The product (A) will be –

(a) RNHCOCH₃

(b) RN(COCH₃)₂

(c) RN(COCH₃ )₃Cl⁻

(d) R – CONH₂

Answer 2

RNHCOCH₃ is the product.

Explanation:

• The substitution of amine with an electrophilic group is very common and instant reaction.

• This substitution extent depends on the concentration of the reactants.

• If amine is in excess, then the monosubstituted product is formed majorly.

• If the amine is the limiting reagent, then the trisubstituted product is the major product.

• Here amine is supplied in excess.

• So the amine gets monosubstituted by the electrophilic group.

• Here the electrophilic group is acyl group.

• The HCl gets eliminated as the reaction progresses.
