JEE Main levelSingle correct optionDifficulty 2 of 3ph062

Match List I with List II. List I: (P) $ClF X_{3}$ , (Q) $BrF X_{5}$ , (R) $IF X_{7}$ , (S) $ICl$ . List II: (1) pentagonal bipyramidal, $s p^{3} d^{3}$ ; (2) square pyramidal, $s p^{3} d^{2}$ ; (3) T-shaped, $s p^{3} d$ ; (4) diatomic, polar.

AP-3, Q-2, R-1, S-4
BP-1, Q-2, R-3, S-4
CP-2, Q-3, R-1, S-4
DP-3, Q-1, R-2, S-4

Answer: A

ClF X_{3}

: 3 bond pairs + 2 lone pairs,

s p^{3} d

, T-shaped.

BrF X_{5}

: 5 bond pairs + 1 lone pair,

s p^{3} d^{2}

, square pyramidal.

IF X_{7}

: 7 bond pairs,

s p^{3} d^{3}

, pentagonal bipyramidal.

ICl

is a polar diatomic molecule. So P-3, Q-2, R-1, S-4.
