MCQ
Identify the reactant $X$ and the product $Y$
  • A
    $X = MgC{l_2};\;\;Y = C{H_3}CH = C{H_2}$
  • B
    $X = C{H_3}MgCl;\;Y = {C_2}{H_5}COC{H_3}$
  • ✓
    $X = C{H_3}MgCl;\;Y = {(C{H_3})_3}\;C - OH$
  • D
    $X = {C_2}{H_5}MgCl;\,Y = {(C{H_3})_3}C - OH$
✓

Answer

Correct option: C.
$X = C{H_3}MgCl;\;Y = {(C{H_3})_3}\;C - OH$
c
(c)$C{H_3}COC{H_3} + \mathop {C{H_3}MgCl}\limits_{{\text{(X)}}}  \to {(C{H_3})_3}C - OMgCl$  $\xrightarrow{{{\text{hydrolysis}}}}{(C{H_3})_3}\mathop {C - OH}\limits_{(Y)}  + Mg(OH)Cl$
