the major product of the following reaction is

The major product of the following reaction is :
\[C{{H}_{3}}CH=CHC{{O}_{2}}C{{H}_{3}}\xrightarrow{LiAl{{H}_{4}}}\]

A. $$C{H_3}C{H_2}C{H_2}C{O_2}C{H_3}$$

B. $$C{H_3}CH = CHC{H_2}OH$$

C. $$C{H_3}C{H_2}C{H_2}C{H_2}OH$$

D. $$C{H_3}C{H_2}C{H_2}CHO$$

Answer : $$C{H_3}CH = CHC{H_2}OH$$

Solution :
$$LiAl{H_4}$$ reduces esters to alcohols but does not reduce $$C = C.$$
\[C{{H}_{3}}CH=CH-C{{O}_{2}}Me\xrightarrow{LiAl{{H}_{4}}}C{{H}_{3}}CH=CHC{{H}_{2}}OH\]
