Vedclass · Answer

(B) The reaction of a Grignard reagent $(R-MgX)$ with carbonyl compounds follows these general rules:$1$. Formaldehyde $(HCHO)$ reacts with a Grignard reagent to form a primary $(1^{\circ})$ alcohol.$2$. Other aldehydes $(R'-CHO)$ react with a Grignard reagent to form a secondary $(2^{\circ})$ alcohol.$3$. Ketones $(R'-CO-R'')$ react with a Grignard reagent to form a tertiary $(3^{\circ})$ alcohol.Among the given options:- $HCHO$ is formaldehyde (forms primary alcohol).- $CH_3CHO$ is acetaldehyde (an aldehyde,forms secondary alcohol).- $CH_3COCH_3$ is acetone (a ketone,forms tertiary alcohol).- $CH_3CH_2COCH_3$ is butanone (a ketone,forms tertiary alcohol).Therefore,$CH_3CHO$ reacts with a Grignard reagent to produce a secondary alcohol.

Which of the following on reaction with Grignard reagent followed by hydrolysis forms a secondary alcohol?
