Dehydration occurs with all the three reagents.
$C_{6} H_{5} C H_{2} C O N H_{2} \overset{P_{2} O_{5}}{\to} C_{6} H_{5} C H_{2} C N + H_{2} O$
$C_{6} H_{5} C H_{2} C O N H_{2} \overset{S O C l_{2}}{\to} C_{6} H_{5} C H_{2} C N + S O_{2} + 2 H C l$
$C_{6} H_{5} C H_{2} C O N H_{2} \overset{P O C l_{3} o r P C l_{5}}{\to} C_{6} H_{5} C H_{2} C N + H_{2} O$
