Step 1
I'll solve this problem step by step, following the specified LaTeX and formatting guidelines:

Step 2
: Determine the total number of valence electrons

- Total valence electrons: $$8 + 6 + 6 = 20$$ electrons
- Carbon (C): 4 valence electrons × 2 = 8 electrons - Oxygen (O): 6 valence electrons × 1 = 6 electrons - Hydrogen (H): 1 valence electron × 6 = 6 electrons

Final Answer

- Each carbon has 4 electrons (single bonds) - Oxygen has 4 electrons in bonds and 4 electrons in lone pairs - All atoms satisfy the octet rule Final Lewis Structure: \begin{array}{c} H_3 C-O-CH_3 \ \text{with two lone pairs on oxygen} \end{array}
