The reaction with H₂ & Raney Ni (Catalytic Hydrogenation) can be used to reduce aldehydes and ketones to alcohols.
An Aldehyde is a functional group which contains the carbonyl group that is -C = O. The structural formula for aldehyde is RCHO.
Reaction of Aldehyde with H₂ & Raney Ni gives Primary alcohol
RCHO + H₂ & Raney Ni → RCH₂OH
A Ketone is a functional group which contains the carbonyl group that is -C = O. The structural formula for ketone is RCOR.
Reaction of Ketone with H₂ & Raney Ni gives Secondary alcohol
RCOR + H₂ & Raney Ni → RCH(OH)R
Thus from the above conclusion we can say that The reaction with H₂ , Raney Ni can be used to reduce aldehydes and ketones to alcohols.
