Question

How does the addition of hydrogen in catalytic hydrogenation differ from hydrogenolysis when applied to Benzyl esters?

Accepted Answer

Catalytic hydrogenation primarily adds hydrogen across pi bonds, while hydrogenolysis breaks C-O bonds.

Answer

Both processes result in the formation of alcohols from esters.

Answer

Catalytic hydrogenation exclusively adds hydrogen to aromatic rings, while hydrogenolysis adds to alkyl chains.

Answer

Both processes add hydrogen to pi bonds, but hydrogenolysis is faster.
