The geometry of CH4 (methane) as predicted by VSEPR is:
ATrigonal planar (3 atoms around C)
BSquare planar (rare 4-coordinate)
CTetrahedral (4 e⁻ pairs at 109.5°)
DPyramidal (3 atoms + 1 lone pair)
Answer & Solution
Correct answer: C. Tetrahedral (4 e⁻ pairs at 109.5°)
CH4 has 4 bond pairs around C (no lone pairs). VSEPR predicts TETRAHEDRAL geometry with 109.5° H-C-H angles. NH3 and H2O are pyramidal/bent because lone pairs distort.
