Question

Match List-I with List-II:

List-I ( Types of hybridisation )		List-II ( Distribution of hybrid orbitals in space )
A	sp$^3$	(I)	Trigonal bipyramidal
B	dsp$^2$	(II)	Octahedral
C	sp$^3$d	(III)	Tetrahedral
D	sp$^3$d$^2$	(IV)	Square Planar

Choose the correct answer from the options given below:

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

Answer 1

The Correct Option is D

To correctly associate hybridization types with their spatial distributions of hybrid orbitals, we must examine the properties of each hybrid and its characteristic geometry.

• sp³ hybridization: This involves the mixing of one s orbital and three p orbitals to generate four identical hybrid orbitals arranged tetrahedrally. Consequently, sp³ corresponds to (III) Tetrahedral.
• dsp² hybridization: This process utilizes one d orbital, one s orbital, and two p orbitals. The typical geometric outcome of this configuration is square planar. Thus, dsp² matches (IV) Square Planar.
• sp³d hybridization: Here, one s orbital, three p orbitals, and one d orbital combine to form five equivalent hybrid orbitals adopting a trigonal bipyramidal geometry. Accordingly, sp³d is matched with (I) Trigonal bipyramidal.
• sp³d² hybridization: Composed of one s orbital, three p orbitals, and two d orbitals, this hybridization yields six equivalent hybrid orbitals arranged octahedrally. The pairing for sp³d² is (II) Octahedral.

The definitive pairings are:

• A-III (sp³ - Tetrahedral)
• B-IV (dsp² - Square Planar)
• C-I (sp³d - Trigonal bipyramidal)
• D-II (sp³d² - Octahedral)

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