In which of the following pairs, both the species are not isostructural?
The electronegativity difference between $\text{N}$ and $\text{F}$ is greater than that between $\text{N}$ and $\text{H}$, yet the dipole moment of $\text{NH}_3$ (1.5 D) is larger than that of $\text{NF}_3$ (0.2 D). This is because:
