Here are the resonance contributors I found.
How many resonance structures or isomers does ch4 have?
2 answers:
Answer : Methane does not has any resonating structures or isomers.
Explanation : Methane has tetrahedral geometry where all the valence bonds of carbon are satisfied with hydrogen atoms which are similar to each other. They also do not produce any lewis dot structure. Therefore, methane cannot have resonating structures.
Answer:
Zero.
Explanation:
Hello,
As long as methane has hydrogen atoms all around the carbon atom sharing four valance electrons to attain the octate in a tetrahedral structure, no matter where the hydrogens get moved, its molecular arrangement will always have the same Lewis structure or 3D projection (attached picture) in this manner, it does not have any resonance structures.
Best regards.

A free-radical substitution reaction is likely to be responsible for the observations. The reaction mechanism of a reaction like this can be grouped into three phases:
- Initiation; the "light" on the mixture deliver sufficient amount of energy such that the halogen molecules undergo homologous fission. It typically takes ultraviolet radiation to initiate fissions of the bonds.
- Propagation; free radicals react with molecules to produce new free radicals and molecules.
- Termination; two free radicals combine and form covalent bonds to produce stable molecules. Note that it is possible for two carbon-containing free-radicals to combine, leading to the production of trace amounts of long carbon chains in the product.
