Vedclass · Answer

(A) Fluorine is a small and highly electronegative atom, which allows it to stabilize higher oxidation states of transition metals effectively.$VF_5$ is stable because the small size of fluorine atoms allows five of them to be accommodated around the vanadium atom without significant steric hindrance.In contrast, $VCl_5$ is unstable because the larger size of chlorine atoms leads to significant steric hindrance, making it difficult for five chlorine atoms to bond with the central vanadium atom.Additionally, the $V-F$ bond has a higher bond enthalpy compared to the $V-Cl$ bond, contributing to the stability of $VF_5$.Therefore, both the assertion and the reason are true, and the reason is the correct explanation for the assertion.

Assertion $(A):$ $VF_5$ is stable while $VCl_5$ is not.
Reason $(R):$ Fluorine stabilizes the higher oxidation state due to its higher bond enthalpy.
The correct option among the following is
