Identify the correct pathway to convert propanoic acid to ethylamine. The reagent represented by A, B and C are

C{H}_{3}C{H}_{2}COOH\overset{A}{→}X\overset{B}{→}Y\overset{C}{→}C{H}_{3}C{H}_{2}N{H}_{2}

Options

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
$HCN$ $N{H}_{3}$ $B{r}_{2} / KOH$

Correct answer

B.

A	B	C
$SOC{l}_{2}$	$N{H}_{3}$	$B{r}_{2} / KOH$

Step-by-step solution

C{H}_{3}C{H}_{2}COOH\overset{SOC{l}_{2} ( A )}{→}\mathop{C{H}_{3}C{H}_{2}COCl}_{( X )}\overset{N{H}_{3}\left(B\right)}{→}\mathop{C{H}_{3}C{H}_{2}CON{H}_{2}}_{( Y )}\overset{B{r}_{2} / KOH ( C )}{→}C{H}_{3}C{H}_{2}N{H}_{2}
