Please correct me if I'm wrong but book show that you can reduce C=O of aldehydes and ketones (not esters...etc Right?) to CH2 with wolff kishner/clemmensen, but some books also show that it is possible with H2/pd.

But wouldn't H2/pd reduce it to alcohols? or does it only reduce aromatic C=O to ch2?
Please can someone clear this up? Thanks alot
