Match List I with List II List I (molecules/ions) List II (No. of lone pairs of e - on central atom) (A) IF 7 I. Three (B) ICl 4 - II. One (C) XeF 6 III. Two (D) XeF 2 IV. Zero Choose the correct answer from the options given below:
Options
- AA - II, B - III, C - IV, D - I
- BA - IV, B - III, C - II, D - I
- CA - II, B - I, C - IV, D - III
- DA - IV, B - I, C - II, D - III
Correct answer
B. A - IV, B - III, C - II, D - I
Step-by-step solution
From the following lewis structures of IF 7 ,   ICl 4 - ,   XeF 6   &   XeF 2 : , , and we can deduce the number of lone pairs as well as the hybridisation of the central atom: IF 7 : zero   lone   pair     sp 3 d 3 ICl 4 - : two   lone   pair       sp 3 d 2 XeF 6 : one   lone   pair     sp 3 d 2 XeF 2 : three   lone   pair     sp 3 d
