Question
The compound which forms acetaldehyde when heated with dilute NaOH is:
✓
Answer
(d) 1, 1 dichloroethane
Explanation: $CH _3 CHCl _2+ OH ^{-} \rightarrow CH _3 CH ( OH )_2 \rightarrow CH _3 CHO + H _2 O$
Gem diols like $\left( CH _3 CH ( OH )_2\right.$ ) are generally not stable. The $2- OH$ group attached to the same C removes $H _2 O$ and forms carbonyl compounds.
