Question

What is the Lewis dot diagram for `C_2H_6`?

Answer 1

`H_3C-CH_3`

Explanation:

Each `C` has `4` valence electrons, and each `H` has the `1`. There are no non-bonded lone pairs, and 7 bonding pairs to distribute. So there are `6xxC-H` bonds (12 electrons) and `1xxC-C` bond; 14 electrons in total as required.
