Question

Match List-I with the List-II

List-I (Hybridization)	List-II (Orientation in Space)
(A) sp3	(I) Trigonal bipyramidal
(B) dsp2	(II) Octahedral
(C) sp3d	(III) Tetrahedral
(D) sp3d2	(IV) Square planar

Choose the correct answer from the options given below:

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

Answer 1

The Correct Option is D

To determine the correct match between the hybridization states in List-I and their corresponding orientations in List-II, we need to understand the geometry associated with each type of hybridization:

1. The sp³ hybridization involves one s and three p orbitals mixing to form four equivalent orbitals. This hybridization results in a tetrahedral geometry, where the bond angles are approximately 109.5°. Therefore, (A) sp³ corresponds to (III) Tetrahedral.
2. The dsp² hybridization involves mixing one d, one s, and two p orbitals. This results in a square planar geometry commonly found in certain transition metal complexes. As such, (B) dsp² matches with (IV) Square planar.
3. The sp³d hybridization involves one s, three p, and one d orbitals mixing to form five hybrid orbitals. This leads to a trigonal bipyramidal geometry, where there are two distinct bond angles. Therefore, (C) sp³d corresponds to (I) Trigonal bipyramidal.
4. The sp³d² hybridization involves one s, three p, and two d orbitals. This combination results in an octahedral geometry, which is symmetrical with bond angles of 90°. Hence, (D) sp³d² matches with (II) Octahedral.

By analyzing the hybridizations and corresponding orientations, we can match List-I and List-II as follows:

List-I (Hybridization)	List-II (Orientation in Space)
(A) sp3	(III) Tetrahedral
(B) dsp2	(IV) Square planar
(C) sp3d	(I) Trigonal bipyramidal
(D) sp3d2	(II) Octahedral

Therefore, the correct answer is A-III, B-IV, C-I, D-II.

Answer 2

\[\text{sp}^3 \rightarrow \text{Tetrahedral}\]
\[\text{dsp}^2 \rightarrow \text{Square planar}\]
\[\text{sp}^3\text{d} \rightarrow \text{Trigonal bipyramidal}\]
\[\text{sp}^3\text{d}^2 \rightarrow \text{Octahedral}\]
