Question

Assertion: Equal number of sigma and pi bonds are present in ethyne.
Reason: pi bond is stronger than sigma bond.

• A. Assertion is true but the reason is false
• B. Assertion and reason both are false
• C. Assertion and the reason are true but reason is not the correct explanation of the assertion
• D. Assertion and reason are true and reason is the correct explanation of the assertion

Answer 1

The correct option is B Assertion and reason both are false

In the case of ethyne we have a total of three sigma and two $\pi$-bonds. Hence, the assertion becomes false. Also, the sigma bond is always stronger than the pi bond due to greater extent of overlapping. So, the reason is also incorrect.
