JEE Main2026Jan 28, Shift 2Chemistry

Match List-I with List-II according to shape.

Choose the correct answer from the options given below :

Solution

Apply VSEPR by counting bond pairs (bp) and lone pairs (lp):

A. XeO $_{3}$ : 3 bp + 1 lp $\Rightarrow$ pyramidal — same shape family as NH $_{3}$ (II).

B. XeF $_{2}$ : 2 bp + 3 lp $\Rightarrow$ linear — same as $[I_{3}]^{-}$ (III).

C. XeO $_{2}$ F $_{2}$ : 4 bp + 1 lp $\Rightarrow$ see-saw — same as SF $_{4}$ (IV).

D. XeOF $_{4}$ : 5 bp + 1 lp $\Rightarrow$ square pyramidal — same as BrF $_{5}$ (I).

$∴$ A-II, B-III, C-IV, D-I.
