Molecular Geometry of Methane (CH₄) - VSEPR Theory

What is the molecular geometry of Methane (CH₄)?

Methane (CH₄) has 4 electron domains around the central C atom: 4 bonding and 0 lone pair(s). The electron domain geometry is tetrahedral, giving a tetrahedral molecular shape with bond angles of approximately 109.5 degrees.

Electron Domain Count

Carbon has 4 bonding domains (one for each C–H bond) and 0 lone pairs = 4 total electron domains.

Electron Domain Geometry

4 electron domains arrange tetrahedrally. With no lone pairs, the arrangement is perfectly symmetric.

Molecular Geometry

All 4 electron domains are bonding pairs, so the molecular geometry is also tetrahedral — a perfect 3D shape.

Bond Angle

The bond angle is exactly 109.5° — the ideal tetrahedral angle. With 4 identical bonds and no lone pairs, there is no distortion.
