Question

A _____ activation energy is required to break the double bonds of unsaturated hydrocarbons. high extreme large low

Answer 1

A large activation energy is required to break the double bonds of unsaturated hydrocarbons.

What are Unsaturated hydrocarbons ?

Unsaturated hydrocarbons are defined as the hydrocarbons in which double or triple bonds are present between two adjacent carbon atoms. They are known as alkenes and alkynes respectively. The general formula for these hydrocarbons is CnH2n and CnH2n-2

• In unsaturated hydrocarbons, more number of bonds are formed, thus the bond strength of the bonds formed will be more because the orbitals come closer to each other.
• As, bond strength of unsaturated hydrocarbons are more. So, more energy will be required to break the bond between them.
