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. _Source: syllabus Chem Ch 4 §4.3 VSEPR Theory_
