Answer
A is false but R is true.
Explanation — Electrovalent compounds cannot disssociate into ions in solid state hence they do not conduct electricity but they are very good conductors of electricity in the molten or in aqueous state. Hence the Assertion (A) is false.
Electrovalent compounds are composed of ions that are held by strong electrostatic force of attraction, which cannot be seperated easily. Hence Reason (R) is true.
