Question

Identify the correct reagents A, B and C to convert propanoic acid to ethylamine.
$C{H}_{3}C{H}_{2}COOH\stackrel{A}{\to }X\stackrel{B}{\to }Y\stackrel{C}{\to }C{H}_{3}C{H}_{2}N{H}_2$

• A.

  A	B	C
  $Ca(OH{)}_2$	Heat	$Pt/H_2$

• B.

  A	B	C
  $SOC{l}_2$	$N{H}_3$	$B{r}_2/KOH$

• C.

  A	B	C
  $HN{O}_2$	$P+I_2$	$LiAl{H}_4$

• D.

  A	B	C
  $HCN$	$N{H}_3$	$B{r}_2/KOH$

Answer 1

The correct option is B

A	B	C
$SOC{l}_2$	$N{H}_3$	$B{r}_2/KOH$

$C{H}_{3}C{H}_{2}COOH\underset{\left(A\right)}{\overset{SOC{l}_2}{\to }}\underset{\left(X\right)}{C{H}_{3}C{H}_{2}COCl}\underset{\left(B\right)}{\overset{N{H}_3}{\to }}$

$\underset{\left(Y\right)}{C{H}_{3}C{H}_{2}CON{H}_2}\underset{\left(C\right)}{\overset{B{r}_2/KOH}{\to }}C{H}_{3}C{H}_{2}N{H}_2$
