Question

Is hydrogen transfer and catalytic hydrogenation same?

(a) Yes

(b) No

I had been asked this question in a job interview.

I want to ask this question from Hydrogen : Introduction in section Hydrogenation of Unit Processes

Answer 1

Right choice is (a) Yes

Easy explanation: Of the above methods the one most frequently confused with catalytic hydrogenation is hydrogen transfer, which involves the saturation of ethylenic double bonds by the direct exchange of hydrogen generally from one substance to another with essentially no participation of free molecular hydrogen. The process is recognized as being separate and distinct from hydrogenation or dehydrogenation and apparently proceeds by an ionic mechanism taking place over an acid catalyst.
