Lewis Structure; Non-bonding pair missing

    1. The problem statement, all variables and given/known data

    2. Relevant equations

    The total number of valence electrons in SOCl2 is 6 + 6 + 7(2) or 26 valence electrons. Dividing by 8, this implies a total of three bonds formed with the central atom (the least electronegative atom, or sulfur).

    3. The attempt at a solution

    However, in my teacher's solution, there appear to only be 24 electrons total. Sulfur seems to be missing an non-bonding pair of electrons.

    Am I correct that there should be a pair of non-bonding electrons on sulfur?

    Yes, indeed. The Sulphur atom has 10 electrons in the vecinity of the nucleus+first shell.
