Why arepentahalides more covalent than trihalides?

Answer»

Solution :Since ELEMENTS in the `+5` oxidation state have less tendency to LOSE electrons than in the `+3` oxidation state, therefore elements in the `+5` oxidation state are more COVALENT than in the `+3` oxidation state. In other WORDS, pentahalides are more covalent than trihalides.
