Vedclass · Answer

(B) The reaction of a Grignard reagent $(RMgBr)$ with an aldehyde $(R'CHO)$ followed by acid hydrolysis $(H_3O^+)$ yields a secondary alcohol.The reaction is:$CH_3CH_2CHO + RMgBr \rightarrow CH_3CH_2CH(OMgBr)R$$CH_3CH_2CH(OMgBr)R + H_3O^+ \rightarrow CH_3CH_2CH(OH)R + Mg(OH)Br$Comparing the product $CH_3CH_2CH(OH)CH_2CH_3$ with the general formula $CH_3CH_2CH(OH)R$,we can see that $R$ must be an ethyl group,$CH_3CH_2-$.Therefore,the correct option is $B$.

In the given reaction,identify $R$ in $RMgBr$:
$CH_3CH_2CHO \xrightarrow[2. H_3O^+]{1. RMgBr} CH_3CH_2CH(OH)CH_2CH_3$
