Question

Which statement is wrong about the hydrolysis of $R-\overset{\oplus}{N} \equiv \overset{\Theta}{C}$ ?

• A. Isocyanides are hydrolysed with aqueous dilute acids but not by alkali.
• B. In the hydrolysis of $(R-\overset{\oplus}{N} \equiv \overset{\Theta}{C})$, first electrophile $\left(H^{\oplus}\right)$ add on the $C$ atom and then nucleophile $(\overset{\Theta}{O}H)$ adds to the same $C$ atom.
• C. On partial hydrolysis, (RNC) gives $N$-substituted methanamide or formamide.
• D. On complete hydrolysis, (RNC) gives $1^{\circ}$ amine and $RCOOH$.

Answer 1

Answer: (B)

Correct answer is (b) In the hydrolysis of $(R-\overset{\oplus}{N} \equiv \overset{\Theta}{C})$, first electrophile $\left(H^{\oplus}\right)$ add on the $C$ atom and then nucleophile $(\overset{\Theta}{O}H)$ adds to the same $C$ atom.
