Q. Identify the correct answer.
A) Dipole moment of $NF_3$ is greater than that of $NH_3$.
B) Three canonical forms can be drawn for $CO_3^{2-}$ ion.
C) Three resonance structures can be drawn for ozone.
D) $BF_3$ has non-zero dipole moment.
Explanation
[Solution by Claude - not from source] $NH_3$ (1.47 D) has a larger dipole moment than $NF_3$ (0.24 D); carbonate has three canonical forms; ozone has two; $BF_3$ is non-polar. Answer (2).
