what are the condensed structured formulas of the products in each of the following reactions:

Question

cyclohexane+ H2-->Pt

and
cis-2-butene+ H2 -->Pt

Answer 1

I can't find anything definite about the first reaction. The second one forms butane.

Answer 2

There is no reaction in the first reaction. It is not possible to reduce cyclohexane further.

And agreed, the second one forms butane.
