CH2 = CH2 + H2 Oversetnirightarrow CH3 - CH3 Is An Addition Reaction. Complete The Following Reaction CH Equiv CH + H2 Oversetnirightarrow?

As given in the question:

CH2 = CH2 + H $\overset{Ni}{\rightarrow}$ CH3 – CH — This is an Addition reaction.

CH ≡ CH + H2 $\overset{Ni}{\rightarrow}$  CH2 = CH2

The second reaction is also an addition reaction. Nickel catalyzed hydrogenation reaction and Alkenee is obtained as the product.
