Q.
In the reaction sequence,
Compound ‘A’ is
A) 1-propanol
B) Propanal
C) Ethanol
D) 2-propanol
Explanation
(b)
Alcohols on reacting with Grignard reagent ($RMgX$) give hydrocarbon on hydrolysis, hence the compound ‘A’ cannot be an alcohol as the product is a oxygen containing compound.
The compound ‘A’ must be propanal. The reaction will be as fallows
