Question

Name the products formed and write an equation when ethyne is added to the following in an inert solvent:

Hydrogen

Answer 1

In the presence of nickel, platinum, or palladium, ethyne changes to ethene and then to ethane.

\[\ce{\underset{Ethyne}{CH ≡ CH} + H2 ->[Ni][300^\circ C] \underset{Ethene}{CH2 = CH2} + H2 ->[Ni][300^\circ C] \underset{Ethane}{CH3 - CH3}}\]
