In which of the following sequences does the final product contain the same number of carbon atoms as the alkyl group R of the Grignard reagent?
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
Grignard 
forms a peroxy magnesium salt → on hydrolysis gives ROOH (no new C's added), so the product has the same number of carbons as R .
With 
acetone, R adds to the carbonyl carbon → products contain R plus extra carbon(s).
