Are alkynes more reactive than alkenes
Correct answer: B. No
- A. Yes
- B. No
- C. Cannot say
- D. Maybe
Explanation
Alkenes are more reactive than alkynes due to their weaker Pi bonds and more exposed electrons in double bonds. This makes them highly susceptible to electrophilic attacks. On the other hand, alkynes have two Pi bonds that are less reactive towards electrophilic reagents, as the short bond distance between triple bonded carbon atoms hinders reactivity. Option B is correct because it accurately explains the reactivity differences between alkynes and alkenes. Options A, C, and D are incorrect as they do not consider the specific structural characteristics that influence reactivity in alkynes and alkenes.

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.
