Why ch4 has a lower boiling point than cf4

Methane,CH4,has a lower boiling point than CF4 because it is a tetrahedral molecule with four equivalent C-H bonds. It's electronic structure is described by four bonding molecular orbitals (MOs) resulting from the overlap of the valence orbitals on C and H. The lowest energy MO is the result of the overlap of the 2s orbital on carbon with the in-phase combination of the 1s orbitals on the four hydrogen atoms.

It is a colorless, natural gas, and can breaks down atom creates CH3 with water vapor that Carbon tetrafluoride,CF4, don't have that has a high bond strength due to its nature of the carbon-fluorine bond and is a potent greenhouse gas.
