what are the classifications? ionic, macromolecular, etc?

a melting point < 100 °C, was soluble in both water and polar organic solvent but insoluble in non polar organic solvent. It conducted electricity in water solution and in molten but not in a solid form.

a melting point > 500°C, was soluble in water and slightly soluble in polar organic but insoluble in non polar organic solvent. It conducted electricity in water solution as well as molten but did not conduct electricity in a solid form

Answer #1

Answer :

Classification :

(1) Polar covalent compound has a melting point of < 100°C . It is soluble in both water and polar organic . It will conduct electricity in molten and in water solution . e.g. Ammonia (NH3) .

Among ionic compound and macromolecular , macromolecular can comes in this category because these consist of covalent bonds.

(2) Ionic compound e.g. NaCl, MgO etc has a melting point of> 500°C and are soluble in water , slightly soluble in polar organic solvent and insoluble in non polar solvent. Also , they conduct electricity in water solution and in molten state

NaCl has a melting point of 800 °C .

MgO has a melting point of > 2500°C.
