Solution: How many σ and π bonds are in the molecule?1. 6 σ ; 1 π 2. 7 σ ; 1 π3. 5 σ ; 2 π4. 5 σ ; 1 π 5. 6 σ ; 2 π

Solution: How many σ and π bonds are in the molecule?1. 6 σ ; 1 π 2. 7 σ ; 1 π3. 5 σ ; 2 π4. 5 σ ; 1 π 5. 6 σ ; 2 π

Problem

How many σ and π bonds are in the molecule?

1. 6 σ ; 1 π 

2. 7 σ ; 1 π

3. 5 σ ; 2 π

4. 5 σ ; 1 π 

5. 6 σ ; 2 π

Solution

We’re being asked the number of σ and π bonds in the given molecule.


Sigma (σ) bonds are the single bonds in molecules. Also, recall that a double bond is composed of 1 σ bond and 1 π bond and a triple bond is composed of 1 σ bond and 2 π bonds. This means in the given molecule:
