the distinguishing features in each case

IIT JEEIIT JEE 1978

Solution:

(i) Melting points Ionic compounds have higher melting points than covalent compounds.
(ii) Boiling points Ionic compounds have higher boiling points than covalent compounds.
(iii) Solubility Ionic compounds have greater solubility in water than a covalent compound.
(iv) Conductivity in aqueous solution Ionic compounds have greater electrical conductivity in aqueous solution while covalent compounds are usually non-conducting
