Question

how many π bonds are in the structure of the organic molecule below?

Explanation:

Step1: Recall the definition of π bonds

A π bond is formed by the side - on overlap of p orbitals. In a double bond, there is 1 π bond and 1 σ bond; in a triple bond, there are 2 π bonds and 1 σ bond.

Step2: Count the double bonds in the molecule

Looking at the structure:

• There is a \(C = O\) double bond (1 π bond).
• There is a \(C = C\) double bond (1 π bond).
• There is a \(C = N\) double bond (1 π bond).
