Which of the following pairs of compounds is isoelectronic and isostructural?

Options

  1. ABeCl 2 ,  XeF 2
  2. BTeI 2 ,  XeF 2
  3. CIBr 2 - ,  XeF 2
  4. DIF 3 ,  XeF 2

Correct answer

C. IBr 2 - ,  XeF 2

Step-by-step solution

(i) IBr 2 − number of the electron in the valence shell = 7 + 7 + 7 + 1 = 22 (ii) BeCl 2 sp 3 d hybridised (linear). Number of the electron in the valence shell = 2 + 7 + 7 = 16 (iii) XeF 2 number of electron in valence shell = 8 + 7 + 7 = 22 (iv) TeI 2 number of the electron in the valence shell = 6+7+7=24 (v) IF 3 number of the electron in the valence shell = 7 + 7 + 7 + 7 = 28 IBr 2 − and XeF 2 both are isostructural and isoelectronic.
