The answer to this question is the "low activation energy". Unsaturated hydrocarbons need a LOW ACTIVATION ENERGY to react. Unsaturated hydrocarbon is a type of hydrocarbons that contain double (called as alkenes) or triple bonds (called as alkynes) and it needs only low activation energy during bonding.

Answer: low activation energy

Explanation:

Activation energy is the extra energy required by the reactants to overcome the energy barrier to convert to products.

Unsaturated hydrocarbons are defined as the hydrocarbons which have double or triple covalent C-C bonds. They are known as alkenes and alkynes respectively. The general formula for these hydrocarbons is [tex]C_nH_{2n}[/tex] and [tex]C_nH_{2n-2}[/tex].

Unsaturated hydrocarbons are more reactive than the saturated ones because of the presence of [tex]\pi-[/tex]bonds. They are weaker than [tex]\sigma-[/tex]bonds and thus can be easily broken and thus require less energy for conversion into products.
