Question

The treatment of acylazide $(RCO{N}_3)$ with acidic or alkaline medium gives

• A. $RCON{H}_2$
• B. $R-N{H}_2$
• C. $RC{H}_{2}N{H}_2$
• D. $RCOCHNH$

Answer 1

Answer: (B)

This reaction is known as curtius rearrangement.
$\mathrm{RCON}{}_3\stackrel{-\mathrm{N}{}_2}{\to }\mathrm{RNCO}$$\stackrel{2\mathrm{NaOH}}{\to }\mathrm{Na}{}_2\mathrm{CO}{}_3+\mathrm{RNH}{}_2$
$1^{\circ }$ amine is formed.
