STANDARD Chemistry Dipole Moment MCQ Question
Type: MCQ-conceptual-Medium
Arrange the following in order of increasing dipole moment: H₂O, H₂S, BF₃
A
BF₃ < H₂S < H₂O
B
H₂S < BF₃ < H₂O
C
H₂O < H₂S < BF₃
D
BF₃ < H₂O < H₂S
Correct Answer
Option A
Detailed Explanation
In BF₃, the dipole moment is zero due to its symmetrical structure. In H₂S and H₂O, due to unsymmetrical structures, a net positive dipole is present. H₂O has a higher dipole moment due to the higher electronegativity of oxygen compared to sulfur.
