Vedclass · Answer

(B) The Grignard reagent $CH_3MgI$ acts as a nucleophile and attacks the carbonyl carbon of the aldehyde group in $(EtO)_2CH-CHO$ to form an intermediate alkoxide.Upon acidic hydrolysis $(H_3O^{+})$,the intermediate alkoxide is protonated to form an alcohol,and the acetal group $(EtO)_2CH-$ is hydrolyzed to an aldehyde group $(-CHO)$.The reaction sequence is: $(EtO)_2CH-CHO + CH_3MgI$ $\rightarrow (EtO)_2CH-CH(OMgI)CH_3$ $\xrightarrow{H_3O^{+}} OHC-CH(OH)CH_3$.

List $-I$ (Products formed)	List $-II$ (Reaction of carbonyl compound with)
$(a).$ Cyanohydrin	$(i).$ $NH_2OH$
$(b).$ Acetal	$(ii).$ $RNH_2$
$(c).$ Schiff's base	$(iii).$ Alcohol
$(d).$ Oxime	$(iv).$ $HCN$

$(EtO)_2CH-CHO + CH_3MgI \xrightarrow{H_3O^{+}} (A)$. The product obtained in the above reaction is:
