Reduction of 3-pentenal with hydrogen in the presence of Raney nickel at 298 K gives

A

`CH_(3)CH=CH-CH_(2)CH_(2)OH`

B

`CH_(3)CH_(2)CH_(2)CH_(2)CH_(2)OH`

C

`CH_(3)CH_(2)CH_(2)CH_(2)CHO`

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
B

At 298 K, `H_(2)//Ni` reduces `-CHO` group to `-CH_(2)OH` group (primary alcohol). The double bond remains unaffected.
`CH_(3)CH=CHCHOoverset(+H_(2)//Ni)underset("298 K")rarrCH_(3)CH=CHCH_(2)CH_(2)OH`
