Question

Why are unsaturated hydrocarbons more reactive than saturated hydrocarbons ?

Answer 1

saturated molecules have only Sigma bonds which are very stable and hard to break. Unsaturated molecules,however, have pi bond and they are weaker. they deform the orbitals slightly and are more strained. Therefore,they are easier to break and will react faster

Answer 2

Unsaturated hydrocarbons have double or triple bond which is weaker than single bong which saturated hydrocarbons have . So it is more reactive
