Why chlorine trifluoride (ClF3) exists but fluorine trichloride (FCl3) does not?

Fluorine trichloride (FCl₃) does not exist due to unavailability of d-orbitals in fluorine atom it cannot expand its valence shell. Therefore it is unable to form FCl₃ whereas Chlorine has vacant d-orbitals. Hence it can promote one of the 3p electrons to the 3-d sub shell and shows +3 oxidation state and forms ClF₃
