Question

How many σ and π bonds are in this molecule? A chain of five carbon atoms. There is a double bond between the first and second carbon atoms and a triple bond between the fourth the fifth carbon atoms. There are single bonds between the remaining carbon atoms. There are two hydrogen atoms bonded to the first carbon atom through single bonds, and a single hydrogen atom bonded to both the second and fifth carbon atoms through single bonds. There is an oxygen atom bonded to the third carbon atom through a double bond.

Answer 1

Answer:

Sigma bonds: 10

Pi bonds: 4

Explanation:

The compound described must be CH2=CH-CO-CH≡CH. If we look at the compound closely, we will notice that there are 10 sigma bonds and 4 pi bonds.

There are three pi bonds between carbon atoms and one pi bond between a carbon and an oxygen atom (C=O). All these can easily be seen in the structure of the formula chosen in this answer.
