A compound 'X' undergoes reduction with ...

A compound 'X' undergoes reduction with `LiAlH_(4)` to yield 'Y'. When vapours of 'Y' are passed over freshly reduced copper at `300^(@)C`, 'X' is formed. What is 'Y' ?

A

`CH_(3)CH_(2)OH`

B

`CH_(3)CHO`

C

`CH_(3)CH_(2)OH`

D

`CH_(3)OCH_(3)`

Text Solution

Verified by Experts

The correct Answer is:
C
Aldehydes are reduced by `LiAlH_(4)` to alcohols and alcohol are oxidised by copper to give aldehydes.
`underset(X)(CH_(3)CHO) to overset(LiAlH_(4)) to underset(Y) (CH_(3)CH_(2)OH) overset(Cu) underset(Delta)tounderset(X)(CH_(3)CHO)`
