Consider the following:
Assertion (A) : Dipole moment of \(\mathrm{NF}_3\) is lesser than \(\mathrm{NH}_3\)
Reason (R) : In NF \({ }_3\), the orbital dipole due to lone pair of electrons is in the opposite direction to the resultant dipole moment of the three N-F bonds
The correct answer is

A Both \((A)\) and \((R)\) are correct and \((R)\) is the correct explanation of \((A)\)
B Both \((A)\) and \((R)\) are correct but \((R)\) is not the correct explanation of \((A)\)
C (A) is correct, but (R) is not correct
D (A) is not correct, but (R) is correct

Answer & Solution

Correct Answer

(A) Both \((A)\) and \((R)\) are correct and \((R)\) is the correct explanation of \((A)\)

Step-by-step Solution

Detailed explanation

NO SOLUTION

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.
