Step 1: Carbon (EN = 2.5) is less electronegative than oxygen (EN = 3.5) so C is the central atom.


Step 2: The total number of valence electrons:


            Group             Valence Electrons

C          4A                   1 × 4 e4 e

H         1A                   4 × 1 e4 e

O         6A                   1 × 6 e6 e

Total:  14 valence e


Step 3: O prefers 2 bonds. The complete Lewis structure of CH3OH is:
