Which of the following will produce only one product on reduction...

Which of the following will produce only one product on reduction with

LiAl{H}_{4} ?

Options

A $C{H}_{3}COOC{H}_{2}C{H}_{3}$
B $C{H}_{3}C{H}_{2}OCOC{H}_{2}C{H}_{3}$
C ${\text{CH}}_{3} {\text{CH}}_{2} {\text{CH}}_{2} {\text{OCOCH}}_{3}$
D $C{H}_{3}C{H}_{2}OCOC{H}_{2}C{H}_{2}C{H}_{3}$

Correct answer

A. $C{H}_{3}COOC{H}_{2}C{H}_{3}$

Step-by-step solution

This ester undergoes reduction with

LiAl{H}_{4}

to give only ethyl alcohol, other esters given in option on reduction gives a mixture of alcohols.

{\text{CH}}_{3} {\text{COOCH}}_{2} {\text{CH}}_{3} + 4\left[\text{H}\right]\mathop{\overset{{\text{LiAlH}}_{4}}{→}}_{\text{ether}} 2{\text{CH}}_{3} {\text{CH}}_{2} \text{OH}
