The C-H bond in methane CH4 is considered to be nonpolar. This is because the electronegativity difference between carbon 2.55 and hydrogen 2.20 is relatively small 0.35 . As a result, the electrons in the bond are shared fairly equally between the two atoms, and there is no significant charge separation or dipole moment. Additionally, methane has a tetrahedral molecular geometry, which means that the bond dipoles cancel each other out, resulting in a nonpolar molecule overall.
