Question

Which of the following molecules has three-fold axis of symmetry? (A) NH3 (B) C2H4 (C) CO2 (D) SO2

Tardigrade Admin · Accepted Answer

In NH3 molecule, the original appearance is repeated as a result of rotation through 120°. Such an axis is said to be an axis of three-fold symmetry or a triad axis.
