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.

Answer 2

The total number of sigma bonds in the given structure are 9. The total number of pi bonds in the given structure are 4.

The given hydrocarbon has the structure of:

$\rm CH_2=CH-C(=O)-C\equiv CH$.

The pie bonds are the unsaturated bonds, formed by the electron clouds. The double and triple bonds are pi bonds.

In the given structure number of pi bonds are:

• 1 pi bond between 1st Carbon and 2nd Carbon

• 1 pi bond between 3rd Carbon and Oxygen

• 2 pi bonds between 4th Carbon and 5th carbon.

Thus the total number of pi bonds in the given structure are 4.

The sigma bonds are the covalent bonds, formed by the sharing of electrons. The single bonds are sigma bonds.

The number of sigma bonds are;

• 1st Carbon has 2 sigma bond with hydrogen and 1 sigma bond with 2nd Carbon.

• 2nd Carbon has 1 sigma bond with hydrogen, and 1 sigma bond with 3rd Carbon

• 3rd Carbon has 1 sigma bond with oxygen, and 1 sigma bond with 4th Carbon

• 4th Carbon has 1 sigma bond with fifth carbon.

• 5th Carbon has 1 sigma bond with hydrogen.

Thus the total number of sigma bonds in the given structure are 9.
