`CH_(3)COOHoverset(LiAlH_(4))(rarr)(A), (A)+CH_(3)COOHoverset(H_(3)O^(+))(rarr)(B)+H_(2)O` . In the above reaction 'A' and 'B' respectively are `:`

Options

A. `CH_(3) COOC_(2)H_(5), C_(2)H_(2)OH`
B. `CH_(3)CHO, C_(2)CHO`
C. `C_(2)H_(5)OH, CH_(3)CHO
D. `C_(2)H_(5)OH, CH_(3) COOC_(2)H_(5)`

Answer

D

Explanation

`CH_(3)COOH+4H overset(LiAl_(4)) to underset(A) (CH_(3)CH_(2)OH)+H_(2)O`
`underset(A) (CH_(3)CH_(2)OH)+CH_(3)COOH overset(H_(3)O^(+)) to underset(B) (CH_(3)BOOC_(2)H_(5))+H_(2)O`
