Question

$Ph-\underset{CN}{\underset{|}{CH}}-\stackrel{O}{\stackrel{||}{C}}-C{H}_3\underset{\left(ii\right)\Delta }{\overset{\left(i\right)H_3{O}^{\oplus }}{\to }}\left(A\right)$

Complete the following.

Answer 1

$Ph-\underset{CN}{\underset{|}{CN}}-\stackrel{O}{\stackrel{||}{C}}-C{H}_3\underset{\left(ii\right)\Delta }{\overset{\left(i\right)H_3{O}^{\oplus }}{\to }}\left(A\right)Ph-\underset{COOH}{\underset{|}{CH}}-\stackrel{O}{\stackrel{||}{C}}-C{H}_3\stackrel{\Delta }{\to }Ph-\underset{H}{\underset{|}{CH}}-\stackrel{O}{\stackrel{||}{C}}-C{H}_3$

• 
  
• Hydrolysis will convert the $CN$ group to $COOH$ of compound $A$
• Heating will Release the $C{O}_2$ gas .
