Alkenes

Question

A. They can only undergo substitution reactions
B. They are more reactive than alkanes
C. They have a higher boiling point than alkanes
D. They cannot form addition polymers

Answer

They are more reactive than alkanes

Explanation

Alkenes are more reactive than alkanes due to the presence of the double bond, which can participate in addition reactions. This increased reactivity is a key characteristic that distinguishes alkenes from alkanes.

Common mistake

Misunderstanding Unsaturation

Students often describe alkenes as saturated hydrocarbons instead of unsaturated hydrocarbons.

Remember that alkenes contain at least one double bond (C=C), which makes them unsaturated. The formula for alkenes is CnH2n, indicating they have fewer hydrogen atoms than saturated hydrocarbons.
