MCQ
If two compounds have the same empirical formula but different molecular formula, they must have
- ADifferent percentage composition
- ✓Different molecular weights
- CSame viscosity
- DSame vapour density
✓
Answer
Correct option: B.
Different molecular weights
b
If two compounds have the same empirical formula but different molecular formula, they must have different molecular weights.
If two compounds have the same empirical formula but different molecular formula, they must have different molecular weights.
For example, $CH _2 O$ and $C _6 H _{12} O _6$ have the same empirical formula but different molecular formula, they have different molecular weights.
