# What is the Lewis dot diagram for C_2H_6?

${H}_{3} C - C {H}_{3}$
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 $6 \times C - H$ bonds (12 electrons) and $1 \times C - C$ bond; 14 electrons in total as required.
