Step 1: Determine the electron geometry of the molecule
The electron geometry for C^2H^4 (ethylene) can be determined by counting the total number of electron groups around the central atom. In this case, the central atom is carbon, and it is bonded to two hydrogen atoms and another carbon atom. Therefore, there are a total of 4 electron groups (2 bonds + 2 lone pairs) around the central carbon atom.
Step 2: Determine the hybridization of the central atom
The hybridization of the central atom can be determined by comparing the number of electron groups and the observed molecular geometry. For 4 electron groups, the hybridization is sp^2. This means that the central carbon atom undergoes sp^2 hybridization.
Final Answer
Trigonal Planar.
