Question

What is the VSEPR geometry of methane (CH4)? How many electron groups surround the central carbon atom and what is the hybridization of the carbon atom in methane?

Answer 1

The VSEPR geometry of methane  CH4  is tetrahedral. There are four electron groups surrounding the central carbon atom, as it is bonded to four hydrogen atoms. The hybridization of the carbon atom in methane is sp3, as it has four sigma bonds with the hydrogen atoms.
