Why do pentahalides exhibit more covalent character than trihalides?
Options
- APentahalides have a higher atomic number
- BPentahalides involve +3 oxidation state
- CPentahalides involve +5 oxidation state
- DIt varies depending on the element
Correct answer
C. Pentahalides involve +5 oxidation state
Step-by-step solution
The covalent character of pentahalides is attributed to the +5 oxidation state, which has more polarizing power compared to +3 oxidation state in trihalides.
