####4. An organic compound $A$ upon reacting with $NH _3$ gives $B$. On heating, $B$ gives $C$. $C$ in the presence of $KOH$ reacts with $Br _2$ to give $CH _3 CH _2 NH _2$. $A$ is

(2013 Main)

(a) $CH _3 COOH$

(b) $CH _3 CH _2 CH _2 COOH$

(c) $CH _3-\underset{CH _3}{CH}-COOH$

(d) $CH _3 CH _2 COOH$

Show Answer

Answer:

Correct Answer: 4. (d)

Solution:

  1. $CH _3 CH _2 \underset{(A)}{\stackrel{O}{C}-OH \xrightarrow{NH _3}}$

(B)

(C)

$$ \underset{\begin{array}{l} \text { Hoffmann’s bromamide } \ \text { reaction } \end{array}}{Br _2, KOH} CH _3-CH _2-NH _2 $$
