Answer:
The orbitals on the carbon atom are hybridized; the bonds result from overlap of carbon hybrid orbitals with hydrogen atomic orbitals
Explanation:
In the formation of methane, carbon atoms are sp3 hybridized. One s orbital in carbon mixes with three p orbitals of carbon to yield a set of four sp3 orbitals which bonds to four hydrogen 1s orbitals by sigma bonds.
The molecule is tetrahedral with a bond angle of 109.5 degrees
