Match each set of hybrid orbitals from LIST-I with complex(es) given in LIST-II.

LIST-I LIST-II

(P) dsp 2 (1) [FeF 6 ] 4–

(Q) sp 3 (2) [Ti(H 2 O) 3 Cl 3 ]

(R) sp 3 d 2 (3) [Cr(NH 3 ) 6 ] 3+

(S) d 2 sp 3 (4) [FeCl 4 ] 2–

(5) Ni(CO) 4

(6) [Ni(CN) 4 ] 2–

The correct option is

P → 5 ; Q → 4, 6 ; R → 2, 3 ; S → 1

P → 5, 6 ; Q → 4 ; R → 3 ; S → 1, 2

P → 6 ; Q → 4, 5 ; R → 1 ; S → 2, 3

P → 4, 6 ; Q → 5, 6 ; R → 1, 2 ; S → 3

Text Solution

Verified by Experts

The correct answer is:

1. FeF 6 4– 3d 6 & weak field ligand

∴ Hybridization is sp 3 d 2

2. [Ti(H 2 O) 3 Cl 3 ] 3d 1 & weak field ligand

∴ Hybridization is d 2 sp 3

3. [Cr(NH 3 ) 6 ] 3+ , 3d 3 & strong field ligand.

∴ Hybridization is d 2 sp 3

4. [FeCl 4 ] 2– 3d 6 & weak field ligand.

∴ Hybridization is sp 3

5. Ni(CO) 4 , 3d 10

∴ Hybridization is sp 3

6. [Ni(CN) 4 ] 2– , 3d 8

∴ dsp 2 hybridization
