$\mathrm{A} \xrightarrow[\text { (ii) } \mathrm{H}_3 \mathrm{O}^{+}]{\text {(i) } \mathrm{NaOH}} \mathrm{B} \xrightarrow[\text { (ii) } \mathrm{H}_2 \mathrm{SO}_4, \Delta]{\text { (i) } \mathrm{EtOH}} \mathrm{C}$
' A ' shows positive Lassaign's test for N and its molar mass is 121.
' B ' gives effervescence with aq. $\mathrm{NaHCO}_3$.
'C' gives fruity smell.
Identify $\mathrm{A}, \mathrm{B}$ and C from the following.

• Correct answer
  A

  
  
• B

  
  
• C

  
  
• D

  
  

Solution

A $\rightarrow$ Benzamide Shows positive Lassaigh's test.
$B \rightarrow$ Benzoic acid gives effervescence with aq.
$\mathrm{NaHCO}_3$.
$\mathrm{C} \rightarrow$ Ester gives fruity smell.

Hence, the correct answer is option: 'A'.
