Noble gases were considered inert before 1962. Prior to this, Bartlett and Lohmann had previously used the highly ionization energy of `O_(2)` is `1165 " kJ mol"^(-1)`, which is almost the same as the value of `IE_(1)` for Xe `(1170 " kJ mol"^(-1))` . Experiments showed that when deep red `PtE_(6)` vapours were mixed with an equal volume of Xe, the gases combined immediately at room temperature to produce a yellow solid. Soon after this, it was found that Xe and F react directly to give Xe-fluorides. Choose the correct answer : The hybridisation state of Xe in `XeOF_(4)` is :A. `sp^(3)`B. `sp^(3)d`C. `dsp^(2)`D. `sp^(3) d^(2)`

Answer» Correct Answer - D
Xe atom in `XeOF_(4) " is " sp^(3)d^(2)` hybridised.
