In which of the following pairs, the central atoms have the same number of lone pairs of electrons?

Options

A. `PCl_(5)`,`BrF_(5)`
B. `XeF_(2)`,`ICl`
C. `XeF_(4)`,`ClO_(4)`
D. `SCl_(4)`,`CH_(4)`

Answer

(b)

Explanation

Valence electronic configuration of `Xe = 5s^(2) 5p^(6)`
Here, 2 electrons are involved in bonding with `F_(2)` to form `XeF_(2)` and remaining lone electrons are 6 (i.e 3 lone pairs).
Valence electronic configuration of `I = 5s^(2) 5p^(2)`
  Here, 1 electron is involved in bonding with Cl to form ICI and remaining lone electrons are 6(i.e., 3 lone pairs).
