Question

Number of $\sigma$ and $\pi$ bonds present in $C{H}_3-CH=CH-C\equiv CH$ are:

• A. $10\sigma ,3\pi$
• B. $10\sigma ,2\pi$
• C. $9\sigma ,2\pi$
• D. $8\sigma ,3\pi$

Answer 1

The correct option is A $10\sigma ,3\pi$

Sigma bonds are formed by axial overlap and pi bonds are formed by sideways overlap. total number of bonds are $10\sigma ,3\pi$.
