Question

Which of the following compounds gives 3 - ethylpentan - 3 - 0l by the action of ethyl magnesium iodide followed by acid hydrolysis?(a) Propanone (b) Butanone(c) Pentan - 2 - one (d) Pentan - 3 - one

Answer 1

answer :- option (d) pentan - 3 - one

explanation :- Grignard reagents (RMgX) react with the carbonyl group, C=O, in aldehydes or ketones to give alcohols.

when pentan-3-one reacts with Grignard reagent , ethyl magnesium iodide (CH3CH2MgI) then, product forms 3-ethylpentan-3-ol.

hence, option (d) is correct.
