Solution

Q.
Identify the correct answer. [2024]

1 Three resonance structures can be drawn for ozone.

2 ${BF}_{3}$ has non-zero dipole moment.

3 Dipole moment of ${NF}_{3}$ is greater than that of ${NH}_{3}$ .

4 Three canonical forms can be drawn for ${CO}_{3}^{2 -}$ ion.

Ans.
(4)

F is more electronegative than H, the resultant dipole moment of ${NH}_{3}$ is much more than that of ${NF}_{3}$ due to its resultant dipole moment.
