Given below are two statements :
Statement I : The presence of weaker $\pi$-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 :
Solution
The $\pi$-bond present is alkenes is weaker than $\sigma$ bond present in alkanes. That makes alkenes less stable than alkanes. Therefore, statement-I is correct.
<br/><br/>
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. Therefore, statement-II is also correct.
