The central atom of a methane molecule is the carbon atom. Four hydrogen atoms are directly bonded to it and there is no lone pairs located in the central atom. Having a tetrahedral shape, every bond angle in methane is equal to 109.5 degrees. Was this answer useful?
The bonds between carbon and hydrogen atoms are also nonpolar, such as the four CâH bonds in a methane molecule (Figure 2.5 d). In a polar covalent bond , the sharing of electrons between two atoms is unequalâthe nucleus of one atom attracts the shared electrons more strongly than the nucleus of the other atom. When polar covalent bonds form, the resulting molecule has a partial negative charge near the atom that attracts electrons more strongly.
