Question

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

Answer 1

Answer:

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

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

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

Answer 2

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.Addition to other aldehydes gives secondary alcohols.
