How many of the following molecules have non-zero net dipole moment?

Question

Canvas Classes · Accepted Answer

Non-zero dipole moment requires asymmetric charge distribution.

Step 1 — Analyse each molecule:

| Molecule | Shape | Dipole moment |
|----------|-------|---------------|
|  | Pyramidal | Non-zero ✓ |
| HCl | Diatomic, polar | Non-zero ✓ |
|  | Bent | Non-zero ✓ |
|  | Linear, symmetric | Zero ✗ |
|  | Trigonal planar, symmetric | Zero ✗ |
|  | Tetrahedral, symmetric | Zero ✗ |

Step 2:  → 3 molecules

Answer: 3
