Exercise 2 | Covalent Bonding

Draw the Lewis structure of ethylene C2H4.

How many σ and π bonds are there in ethylene?

What is the hybridization of the carbon atoms and the shape around them?

Ethylene : 4 single C-H bonds (= 4 σ bonds) + 1 double C=C bond (= σ sigma + 1 π bonds)
⇒ 5 σ bonds + 1 π bond

3 electron groups around carbon atoms = sp2 ⇒ trigonal planar
