Answer & Solution

Correct Answer

(A) (iii) & (iv) only

Step-by-step Solution

Detailed explanation

So we know the concept of dipole moment that it is depends on the charge and distance between central atom and side atoms But the charge is more prominent then distance It is determining as polar and non polar molecules It is used for covalent or ionic molecule…

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.
