711.

Number of isomeric primary amines obtained from C₄H₁₁N are :

712.

Which of the following amines will not give N₂ gas on treatment with nitrous acid (NaNO₂ + HCl)?

RCOCl

In acid derivatives acid chlorides is most reactive , it is vigorously hydrolysed by water .

CH₃COCl + H₂O $\to$ CH₃COOH + HCl

Acid anhydride is less reactive than acid chlorides .It is hydrolysed slowly by water .

(CH₃CO)₂O + H₂O $\overset{slow}{\to}$ 2CH₃COOH

The hydrolysis of ethyl acetate in boiling water is slow but inthe presence of acid or alkali the reaction is fast .

CH₃CO-OC₂H₅ + H₂O $\overset{H^{+}}{⇌}$ CH₃COOH + C₂H₅OH

Amides are hydrolysed by water very slowly .

R- $\overset{\underset{| |}{O}}{C}$ -NH₂ + H₂O $\overset{H^{+}}{\to}$ R-COOH + NH₃

Thus , the correct order of hydrolysis is

RCOCl > (RCO)₂O > RCOOR > RCONH₂

The reaction

is called

715.

Which of the following amines, can give N-nitrosoamine on treatment with HNO₂?
