Which of the following is not an ionic halide ?

Answer»

`UF_(4)`
`PbCl_(2)`
`SnCl_(2)`
`UF_(6)`

Solution :`UF_6` has ESSENTIALLY covalent character. This is because small HIGHLY charged cations POLARISE the anions more efectively. For a metal with variable oxidation states, the halide with higher oxidation state of metal will be more covalent than the halide with lower oxidation of the metal. For example, `PbCl_6, SnCl_4 and UF_6`, are more covalent in nature than `PBCI_2, SnCl_2 and UF_4` respectively.
