Options

A. `{:(CH_(3)-CH-COOH),(" |"),(" "OCH_(3)):}`
B. `{:(CH_(3)-CH_(2)-CH-COOH),(" |"),(" "OH):}`
C. `{:(CH_(3)-CH_(2)-CH-COOH),(" |"),(" "CH_(2)OH):}`
D. `{:(CH_(3)-CH-CH_(2)-COOH),(" |"),(" "OH):}`

Answer

C

Explanation

`{:(CH_(3)-CH_(2)-CH-COOH " "overset(LiAlH_(4))to" "CH_(3)-CH_(2)-CH-CH_(2)-OH),(" | |"),(" "CH_(2)OH" "CH_(2)-OH),(" optically active Optically inactive"):}`
