Match List-I with List-II

List-I (Molecule)
(A)

BrF_{5}

(B)

H_{2} O

(C)

ClF_{3}

(D)

SF_{4}

List-II (Shape)
(I) T-shape
(II) See saw
(III) Bent
(IV) Square pyramidal

Answer: A → IV, B → III, C → I, D → II

Solution

Br F_{5}

: 5 bond pairs + 1 lone pair on an octahedral base

\to

square pyramidal.

H_{2} O

: 2 bond pairs + 2 lone pairs on a tetrahedral base

\to

bent.

Cl F_{3}

: 3 bond pairs + 2 lone pairs on a trigonal-bipyramidal base

\to

T-shaped.

S F_{4}

: 4 bond pairs + 1 lone pair on a trigonal-bipyramidal base

\to

see-saw.

So A-IV, B-III, C-I, D-II.

Structure BrF5 structure — BrF5 structure

Structure H2O structure — H2O structure

Structure ClF3 structure — ClF3 structure

Structure SF4 structure — SF4 structure
