# What kind of compound is produced by the hydrogenation of an aldehyde or a ketone?

$\text{Aldehyde/Ketone"rarr1^@"/"2^@"alcohol"rarr"alkane}$
Aldehydes and ketones can be reduced back to their parent alcohols, typically by a hydride transfer reagent such as $L i A l {H}_{4}$. Dihydrogen gas would also achieve the same result with suitable catalysis.
