Question

Compare covalent characters of trihalides and penta halides of nitrogen family

Answer 1

$\huge\textbf{Answer}$


According to Fajan Rule; greater the oxidation state; higher will be the polarisation power and high will be the covalent character.

That's why penta halides are more covalent.


» Fajan Rule :-

Charge on cation $\alpha$ $\dfrac{1}{size\:of\:cation}$ $\alpha$ Polarisation power $\alpha$ Covalent character.
