Question

Which of the following molecules is(are) polar ? I. NH₃ (trigonal pyramidal) II. SO₃ (trigonal planar) III. ClF₃ (T-shaped)

Quizplus · Accepted Answer

I and III are polar due to their asymmetrical shapes (trigonal pyramidal and T-shaped, respectively) which leads to a net dipole moment. II is nonpolar because its symmetrical trigonal planar shape allows for even distribution of charge.
