Question

Which of the following will produce only one product on reduction with $LiAl{H}_4$ ?

• A. ${\text{CH}}_3{\text{COOC}}_2{\text{H}}_5$
• B. ${\text{CH}}_3{\text{COOCH}}_2{\text{CH}}_2{\text{CH}}_{\text{3}}$
• C. ${\text{CH}}_3{\text{CH}}_2{\text{COOCH}}_2{\text{CH}}_3$
• D. ${\text{CH}}_3{\text{CH}}_2{\text{COOCH}}_3$

Answer 1

Answer: (A)

$LiAl{H}_4$ in ether reduces ethyl acetate into ethyl alcohol.

${\text{CH}}_{\text{3}}{\text{COOC}}_{\text{2}}{\text{H}}_{\text{5}}\text{+4[H]}\stackrel{{\text{LiAlH}}_{\text{4}}}{\to }\text{2}{\text{CH}}_{\text{3}}{\text{CH}}_{\text{2}}\text{OH}$
