1.	(a) Write the structures of A, B, C and D in the following reactions: CH3CN(i)SnCl2−HCl−−−−−−−−−→(ii)H2OAdil.NaOH−−−−−−→BHeat−−−→C ↓HCN D (b) Distinguish between: (i) C6H5−CH=CH−COCH3 and (ii) CH3CH2COOH and HCOOH (c) Arrange the following in the increasing order of their boiling points: CH3CH2OH, CH3COCH3, CH3COOH
Answer» (a) Write the structures of A, B, C and D in the following reactions: $\begin{matrix} C H_{3} C N & (i) S n C l_{2} - H C l - -------- \to (i i) H_{2} O A d i l . N a O H - ----- \to & B H e a t - -- \to & C ↓ H C N D \end{matrix}$ (b) Distinguish between: (i) $C_{6} H_{5} - C H = C H - C O C H_{3}$ and (ii) $C H_{3} C H_{2} C O O H$ and $H C O O H$ (c) Arrange the following in the increasing order of their boiling points: $C H_{3} C H_{2} O H, C H_{3} C O C H_{3}, C H_{3} C O O H$
