Vedclass · Answer

(C) The Victor Meyer test gives a blue color for secondary alcohols. This means compound $B$ must be a secondary alcohol. Only aldehydes (other than formaldehyde) react with Grignard reagents to form secondary alcohols. Since the Grignard reagent is methyl magnesium iodide $(CH_3MgI)$,the aldehyde $A$ must be acetaldehyde $(CH_3CHO)$ to produce isopropyl alcohol $(CH_3CH(OH)CH_3)$ as the secondary alcohol $B$.Reaction:$CH_3CHO + CH_3MgI \rightarrow CH_3CH(OMgI)CH_3$$CH_3CH(OMgI)CH_3 + H_2O/H^+ \rightarrow CH_3CH(OH)CH_3 + Mg(OH)I$Isopropyl alcohol $(CH_3CH(OH)CH_3)$ is a secondary alcohol,which gives a blue color in the Victor Meyer test.

An organic compound $A$ reacts with methyl magnesium iodide to form an addition product,which on hydrolysis gives compound $B$. Compound $B$ gives a blue color in the Victor Meyer test. What are compounds $A$ and $B$ respectively?
