    Chlorine has vacant d orbitals hence it can show an oxidation state of +3. Fluorine has no d orbitals, it cannot show positive oxidation state. Size of chlorine atom is greater due to smaller size of fluorine atom it cannot accommodate three large chlorine atoms. Hence ClF3 exists but FCl3 does not exist.
