Which one of the following alkenes will react faster with H ₂ under catalytic hydrogenation conditions?

Correct answer

0

Step-by-step solution

Due to steric hinderence, hyperconjugation and heat of hydrogenation, reactivity of alkenes can be shown as: aligned & H ₂ C = CH ₂> R - CH = CH ₂> & R - CH = CH - R > R ₂ C = CH ₂> & R ₂ C = CHR > R ₂ C = CR ₂ . aligned Related Theory The relative rates of hydrogenation decrease with the increase of steric hindrance. In order of stability of alkene, most stable the alkene slowly it gives the product.
