Subjective Type

Answer the following question: $$ClF_{3}$$ exists but $$FCl_{3}$$ does not. Explain.

Solution

This happens due to the following reasons:
a). $$Cl$$ has vacant $$d-orbitals$$ and hence can show an oxidation state of $$+3$$ but $$F$$ has no $$d-orbitals$$, so, it cannot show positive oxidation states. Since $$F$$ can show only $$-1$$ oxidation state, $$FCl_{3}$$ does not exist.

b). Because of bigger size, $$Cl$$ can accommodate three small $$F$$ atoms around it while $$F$$ being smaller cannot accommodate three large sized $$Cl$$ atoms around it.
