Aldehydes Ketones Question 232
Question: Identify Z in the following reaction sequence. $ CH_3CHO\xrightarrow[Dil.H_2SO_4]{MnO_4^{-}}X\xrightarrow{SOCl_2}Y\xrightarrow[\Delta ]{CH_3COONa}Z $
Options:
A) $ CH_3COCH_2COONa $
B) $ {{(CH_3CO)}_2}O $
C) $ CH_3CO-O-COCH_2Cl $
D) $ CH_3CO-OCOCHCl_2 $
Show Answer
Answer:
Correct Answer: B
Solution:
[b] $ CH_3CHO\xrightarrow{MnO_4^{-}/{H^{+}}}\underset{X}{\mathop{CH_3COOH}}\xrightarrow{SOCl_2} $
$ \underset{Y}{\mathop{CH_3COCl}}\xrightarrow[heat]{CH_3COONa}\underset{Z}{\mathop{CH_3COOCOCH_3}} $
