| Mistake | Correction | |---------|-------------| | Assuming all polar bonds = polar molecule | Check molecular symmetry (e.g., CCl₄ has polar bonds but is non-polar). | | Forgetting LDF exists in all molecules | When comparing molecules with similar dipole/H-bonding, compare LDF (molar mass/size). | | Thinking H-bonding = bond within a molecule | It is an force, not a bond inside one molecule. | | Equating melting point with bond strength only | For molecular compounds, melting point depends on IMF, not covalent bond strength. |
Neon is smaller than fluorine because despite having more electrons, the proton pull is stronger with no electron-electron repulsion gain. Your solution must state this. nelson chemistry 12 solutions chapter 1
