Question

write the mechanism when aldehyde reacts grignard reagent give secondary alcohol 3mark​

Answer 1

Organolithium or Grignard reagents react with the carbonyl group, C=O, in aldehydes or ketones to give alcohols. The substituents on the carbonyl dictate the nature of the product alcohol.

Answer 2

The Grignard Reaction is the addition of an organomagnesium halide (Grignard reagent) to a ketone or aldehyde, to form tertiary or secondary alcohol, respectively.

The reaction of Grignard Reagent with aldehyde leads to the formation of primary alcohol.

The reaction of Grignard Reagent with ketone leads to a formation of a secondary alcohol.
