Answer to Question #101880 in General Chemistry for Greg

Question

Describe how the existence of bonding and nonbonding electrons affect the bond angle of the C2H2 molecule

Answer 1

The chemical bonding in C2H2 consists of sp–sp overlap between the two carbon atoms forming a σ bond and two additional π bonds formed by p–p overlap. Each carbon also bonds to hydrogen in a σ s–sp overlap at 180° angles.
