a) Explain while carbon is bonded to 4 hydrogen atoms to form CH4, the 2s and the three 2p orbitals undergo hybridization to form four sp3 orbitals.
b) By hybridization of the carbon atom, a total of four lone electron orbital sites are established. These sites are described p4 orbitals.
c) Making four bonds lowers the potential energy for the system.
d) The pragmatic geometry for the methane molecule is tetrahedral. Each bond angle is exactly 109.5°.
