हिन्दीThe number of sigma (\( \sigma \)) and pi (\( \pi \)) bonds in pent-2-en-4-yne is
Correct answer · Option 4
\( 10\text{ }\sigma \text{ bonds and } 3\text{ }\pi \text{ bonds} \)
Explanation
Structure of pent-2-en-4-yne is \( \text{HC}\equiv\text{C}-\text{CH}=\text{CH}-\text{CH}_3 \). Total single bonds (\( \sigma \)) = 10, double bond has 1 \( \sigma \) and 1 \( \pi \), triple bond has 1 \( \sigma \) and 2 \( \pi \). Total \( \sigma = 10 \), total \( \pi = 3 \).
