NEETChemistryHydrocarbons
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.
Options
- ABoth 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.
Correct answer
A. Both Statement I and Statement II are correct.
Step-by-step 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.
