${CH}_{3} Cl$ $"CH"_3"Cl"$ has the symmetry elements ${E, C}_{3}$ $"E, C"_3$ , and $σ_text(v)$ .

$"CH"_3"Cl"$ belongs to the $"C"_text(3v)$ point group.

It has the symmetry element $"E, a C"_3$ axis, and three $σ_text(v)$ planes.

The $"C"_3$ axis.

The structure of $"CH"_3"Cl"$ is

CH3Cl

The molecule has a $"C"_3$ axis that includes the $"C-Cl"$ bond.

The three-fold axis may be more evident if you look down the $"C-Cl"$ bond with the $"Cl"$ atom closest to your eye.

C3v

You can rotate the molecule 120° left or right and get a new configuration that is indistinguishable from the original.

$sigma_text(v)$ planes

A second view of the molecule shows that the screen is a $σ_text(v)$ plane.

The plane of the screen includes a $"Cl-C-H"$ bond.

A reflection converts the molecule into a form that is indistinguishable from the original.

The top-down view shows all three mirror planes:
