Problem: Which classes of hydrocarbons react rapidly at room temperature by addition reactions? a) alkanes and alkynes b) alkanes and alkenes c) alkenes and alkynes d) aromatics and alkenes e) alkanes and aromatics

FREE Expert Solution

We are asked which classes of hydrocarbons react rapidly at room temperature by addition reactions.


Addition reactions require pi bonds for the reactant.

  • Note: Aromatic compounds are considered different due to unique stability and thus require different conditions.


Alkane → All single bonds hydrocarbon

Alkene →  hydrocarbon with double bonds (1 pi bond)

Alkyne →  hydrocarbon with triple bonds (2 pi bonds)
