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 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.
View answer and explanation
Correct option: A
Both Statement I and Statement II are correct.
Option A (Both Statement I and Statement II are correct) is correct because alkenes are indeed less stable due to weaker pi bonds, and the overall double bond strength is greater than a single bond.
