Question

Given below are two statements.
Statement I: The presence of weaker π-bonds make alkenes less stable than alkanes.
Statement II: The strength of the double bond is greater than that of carbon-carbon single bond.
In the light of the above statements, choose the correct answer from the options given below.

• A. Both Statement I and Statement II are correct.
• B. Both Statement I and Statement II are incorrect.
• C. Statement I is correct but Statement II is incorrect.
• D. Statement I is incorrect but Statement II is correct.

Answer 1

Answer: (A)

Both Statement I and Statement II are correct.

Answer 2

The $π-bond$ present is alkenes is weaker than $σ-bond$ present in alkanes.
That makes alkenes less stable than alkanes.

Hence, statement-I is correct.

Carbon-carbon double bond is stronger than Carbon-carbon single bond because more energy is required to break 1 sigma and 1 pi bond than to break 1 sigma bond only.

Hence, statement-II is also correct.

Therefore, the correct option is**(A): Both Statement I and Statement II are correct.**
