STANDARD Chemistry Hybridisation MCQ Question

Type: MCQ-conceptual-Medium-Class 11

Which of the following pairs have different hybridisation and same shape? (i) NO₃⁻ and CO₃²⁻ (ii) SO₂ and NH₂⁻ (iii) XeF₂ and CO₂ (iv) H₂O and NH₃

A

(i) and (iv)

B

(ii) and (iv)

C

(ii) and (iii)

D

None of these

Correct Answer

Option C

Detailed Explanation

(i) NO₃⁻ and CO₃²⁻ both have sp² hybridization and trigonal planar shape. (ii) SO₂ has sp² hybridization and bent shape, while NH₂⁻ has sp hybridization and linear shape. (iii) XeF₂ has sp³d hybridization and linear shape, while CO₂ has sp hybridization and linear shape. (iv) H₂O has sp³ hybridization and angular shape, while NH₃ has sp³ hybridization and pyramidal shape. Therefore, (ii) and (iii) have different hybridisation and same shape.
