Which of the following statement is not about ionic solid

A The constituent particles of ionic solid are cations and anions.
B Ionic solids are hard and brittle.
C In this constituent particles are held together by electrostatic force of attraction.
D Pure ionic solid is good conductor of electricity in solid state.

Verified Solution

Answer & Solution

Correct Answer

(D) Pure ionic solid is good conductor of electricity in solid state.

Step-by-step Solution

Detailed explanation

Ionic solids are bad conductor of electricity

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.
