Exemplar Problems

Problem 1 : Each carbon atom in C₂H₄ is sp² hybridized, and the geometry around each carbon is trigonal planar.
Solution :

In ethene (C₂H₄), each carbon atom forms three sigma (σ) bonds. This requires hybridization of the carbon atoms’ atomic orbitals. The carbon atoms in C₂H₄ are sp² hybridized, which results in a trigonal planar geometry around each carbon atom.
