We’re being asked to determine thenumber of π bonds in C2H4. For this, we first need to draw the Lewis structure of C2H4. The steps in drawing Lewis structures are as follows:
Step 1: Determine the central atom in this molecule.
Step 2: Calculate the total number of valence electrons present.
Step 3: Draw the Lewis structure for the molecule.
How many pi bonds are formed when sp3 hybridization occurs in ethene, C2H4?
