Choose the incorrect statement from the following:
A. Isoelectronic molecules/ions have the same bond order.
B. Dipole moment of \(\mathrm{NH}_3\) is greater than that of \(\mathrm{NF}_3\).
C. The Carbon in Methyl Carbocation is \(\mathrm{sp}^3\) hybridised.
D. The stability of an ionic compound is measured in terms of its lattice enthalpy and not simply based on attaining Octet configuration.

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
