Question

Answer the following question:
$ClF_3$ exists but $FCl_3$ does not. Explain.

✓

Answer

$Cl$ 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.
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.
