Q14 / 90 · JEE Main 2022 (24 Jun Shift 2) · Chemistry
Given below are two statements.
Statement I: The presence of weaker -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.

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.
- Correct answerABoth Statement I and Statement II are correct.
- BBoth Statement I and Statement II are incorrect.
- CStatement I is correct but Statement II is incorrect.
- DStatement I is incorrect but Statement II is correct.
Solution
As sigma bond is formed along the internuclear axis it is stronger than pi-bond, and due to the presence of pi-bonds alkenes will be more reactive towards electrophilic reagents.Hence they are less stable than alkanes.
The strength of carbon-carbon double bond is greater than single bond as bond strength is directly proportional to bond order.
Hence, both the statements are correct.
Hence, the correct answer is option: 'A'.
