In catalytic hydrogenation, what are the main key points to remember?

-H2 is added to an ALKENE in presence of a metal catalyst (such as Pt, Pd, Ni)

-Alkene is turned to ALKANE

There is SYN formation of the added protons

What is ABSENT during catalytic hydrogenation?

There is NO regioselectivity NOR rearrangements

How do MESO compounds affect catalytic hydrogenatio?

If the BEGINNING alkene is SYMMETRICAL, a meso product is likely to form. Only ONE product will be shown as they are NOT enantiomers
