Match the reactants in Column-$I$ with the major products in Column-$II$ obtained after the reaction.
Column-$I$ (Reactants) Column-$II$ (Major Product) $A$. $HCHO \xrightarrow{(i) CH_3MgBr, (ii) H_2O}$ $i$. $C_6H_5CHOHCH_3$ $B$. $C_6H_5CHO \xrightarrow{(i) CH_3MgBr, (ii) H_2O}$ $ii$. $(CH_3)_3COH$ $C$. $CH_3COCH_3 \xrightarrow{(i) CH_3MgBr, (ii) H_2O}$ $iii$. $CH_3CHOHCH_3$ $D$. $CH_3CHO \xrightarrow{(i) CH_3MgBr, (ii) H_2O}$ $iv$. $CH_3CH_2OH$
| Column-$I$ (Reactants) | Column-$II$ (Major Product) |
| $A$. $HCHO \xrightarrow{(i) CH_3MgBr, (ii) H_2O}$ | $i$. $C_6H_5CHOHCH_3$ |
| $B$. $C_6H_5CHO \xrightarrow{(i) CH_3MgBr, (ii) H_2O}$ | $ii$. $(CH_3)_3COH$ |
| $C$. $CH_3COCH_3 \xrightarrow{(i) CH_3MgBr, (ii) H_2O}$ | $iii$. $CH_3CHOHCH_3$ |

(A-IV, B-I, C-II, D-III) The reaction of Grignard reagent $(CH_3MgBr)$ with carbonyl compounds followed by hydrolysis yields alcohols:
$A$. $HCHO + CH_3MgBr \rightarrow CH_3CH_2OH$ (Primary alcohol,$iv$)
$B$. $C_6H_5CHO + CH_3MgBr \rightarrow C_6H_5CH(OH)CH_3$ (Secondary alcohol,$i$)
$C$. $CH_3COCH_3 + CH_3MgBr \rightarrow (CH_3)_3COH$ (Tertiary alcohol,$ii$)
$D$. $CH_3CHO + CH_3MgBr \rightarrow CH_3CH(OH)CH_3$ (Secondary alcohol,$iii$)
Therefore,the correct matching is: $A-iv, B-i, C-ii, D-iii$.
$A$. $HCHO + CH_3MgBr \rightarrow CH_3CH_2OH$ (Primary alcohol,$iv$)
$B$. $C_6H_5CHO + CH_3MgBr \rightarrow C_6H_5CH(OH)CH_3$ (Secondary alcohol,$i$)
$C$. $CH_3COCH_3 + CH_3MgBr \rightarrow (CH_3)_3COH$ (Tertiary alcohol,$ii$)
$D$. $CH_3CHO + CH_3MgBr \rightarrow CH_3CH(OH)CH_3$ (Secondary alcohol,$iii$)
Therefore,the correct matching is: $A-iv, B-i, C-ii, D-iii$.
