NEET 2024 Chemistry Resonance and Dipole Moment MCQ Question
Type: MCQ-conceptual-Medium-Class 11
Identify the correct answer.
A
Dipole moment of NF₃ is greater than that of NH₃.
B
Three canonical forms can be drawn for CO₃²⁻ ion.
C
Three resonance structures can be drawn for ozone.
D
BF₃ has non-zero dipole moment.
Correct Answer
Option B
Detailed Explanation
Ozone (O₃) has three resonance structures due to the delocalization of electrons. NF₃ has a lower dipole moment than NH₃ due to the opposing direction of the lone pair dipole. BF₃ is nonpolar as it is symmetrical.
