Question

Assertion (A): Polar covalent compounds can form ions when dissolved in water.

Reason (R): Electrovalent compounds show dissociation.

पर्याय

• Both A and R are true and R is the correct explanation of A.

• Both A and R are true but R is not the correct explanation of A.

• A is true but R is false.

• A is false but R is true.

Answer 1

Both A and R are true but R is not the correct explanation of A.

Explanation:

Assertion A is true because polar covalent compounds form ions in water through ionisation. Reason R is also true because electrovalent compounds undergo dissociation, in which their pre-existing ions separate. These are different processes, so R does not explain the ion formation of polar covalent compounds.
