Electrovalent compounds do not have [CPMT 1991] (a) High M.P. and Low B.P. (b) High dielectric constant (c) High M.P. and High B.P. (d) High polarity
Correct option is A) Electrovalent compound is formed by total transfer of electrons, while covalent bond is formed by sharing electrons. So, electrovalent bond is stronger than covalent. As a result, electrovalent compound has a high melting point and boiling point. Hence option A is the answer.
