The number of non-polar molecules from the following is

Question

Canvas Classes · Accepted Answer

Non-polar molecules have zero net dipole moment (symmetric charge distribution).

Step 1 — Analyse each molecule:

| Molecule | Shape | Dipole moment |
|----------|-------|---------------|
| HF | Diatomic, polar | Non-zero ✗ |
|  | Bent | Non-zero ✗ |
|  | Bent | Non-zero ✗ |
|  | Homonuclear diatomic | Zero ✓ |
|  | Linear, symmetric | Zero ✓ |
|  | Tetrahedral, symmetric | Zero ✓ |
|  | Pyramidal | Non-zero ✗ |
| HCl | Diatomic, polar | Non-zero ✗ |
|  | Tetrahedral, asymmetric | Non-zero ✗ |
