Alkynes have a _ boiling point than alkanes
Correct answer: B. Higher
- A. Lower
- B. Higher
- C. Moderate
- D. No change
Explanation
Alkynes have a higher boiling point than alkanes because of their linear structure and triple bond, resulting in stronger intermolecular forces like dipole-dipole interactions and London dispersion forces. This requires more energy to overcome, leading to a higher boiling point for alkynes. The incorrect options incorrectly suggest a lower or moderate boiling point for alkynes, which is not the case based on their molecular structure and intermolecular forces.

About Chemistry of Hydrocarbons
Hydrocarbons are studied through the structures and reactions of alkanes, alkenes, alkynes and aromatic compounds. Coverage includes free radical substitution in alkanes, electrophilic addition to carbon-carbon multiple bonds, benzene substitution, aromatic stability and the difference between addition reactions of alkenes and substitution reactions of benzene.
