According to VSEPR theory, the geometry of CH₄ around the carbon atom is:
ATetrahedral
BSquare planar
CTrigonal bipyramidal
DOctahedral
Answer & Solution
Correct answer: A. Tetrahedral
1. Carbon in CH₄ has four bond pairs and zero lone pairs.
2. Four equivalent regions of electron density → tetrahedral arrangement.
3. Bond angle is 109.5°.
4. Square planar (90° + 90°) is what 4 bond pairs + 2 lone pairs would give.
