WebJan 23, 2024 · Hydrogenation of Alkenes. Addition of hydrogen to a carbon-carbon double bond is called hydrogenation. The overall effect of such an addition is the reductive … WebOn the right is a di-substituted alkene. Now we have two alkyl groups and the di-substituted alkene is more stable than the mono-substituted alkene. To explain why, we need to go back to the idea of stability of carbocations that we saw in an earlier video. On the right we have a secondary carbocation.
