How many resonance structures can be drawn for methane?

A) 2
B) 3
C) 4
D) None of the above

Methane (CH4) has a tetrahedral structure with single bonds between carbon and hydrogen atoms and does not have any delocalized electrons, so it cannot have resonance structures. Resonance structures are possible only in molecules with delocalized electrons, typically found in molecules with double bonds, lone pairs adjacent to double bonds, or in aromatic systems.
