Question

How many $\sigma -$ and $\pi -$ bonds are there in

• A. $14\sigma ,8\pi$
• B. $18\sigma ,8\pi$
• C. $19\sigma ,4\pi$
• D. $14\sigma ,2\pi$

Answer 1

The correct option is C $19\sigma ,4\pi$

1-phenylprop-1-ene has $19\sigma ,4\pi$ bonds in its structure. 3$\pi$ bonds in benzene ring and 1 is out isde the ring.

So, answer is C.
