Vedclass · Answer

(A) The reaction of propanone $(CH_3COCH_3)$ with ethyl magnesium bromide $(CH_3CH_2MgBr)$ is a Grignard reaction. $1$. Nucleophilic attack: The ethyl group $(CH_3CH_2^-)$ from the Grignard reagent attacks the electrophilic carbonyl carbon of propanone to form an alkoxide intermediate: $CH_3COCH_3 + CH_3CH_2MgBr \rightarrow CH_3C(OMgBr)(CH_2CH_3)CH_3$. $2$. Hydrolysis: Subsequent hydrolysis of the intermediate with water $(H_2O/H^+)$ yields the tertiary alcohol: $CH_3C(OMgBr)(CH_2CH_3)CH_3 + H_2O \rightarrow CH_3C(OH)(CH_2CH_3)CH_3 + Mg(OH)Br$. $3$. The product is $2-$methylbutan$-2-$ol.
