Chloromethane

Chloromethane - ClCH₃:

---

In this molecule the three hydrogens are symmetrically arranged about a line drawn though the line-of-centers of the carbon and chlorine atoms i.e, a C₃ axis.



---

There are also three sv planes containing the chlorine, the carbon, and one of the hydrogen's - these planes also contain the C₃ axis.





Chloromethane's Symmetry Elements are:
One C₃ axis of rotation.
Three sv planes of reflection containing the C₃ axis.
