State the reason why carbon can neither form C4+ cations nor C4− anions but forms covalent compound Also state the reason to explain why covalent compounds: (i) Are bad conductors of electricity. (ii) Have low melting and boiling points.
Why do covalent compounds have low melting and boiling points ?
Explain the following: (a) Covalent compounds are generally gases or liquids or soft solids. (b) Covalent compounds have low melting point and boiling point. (c) Non-polar covalent compounds are insoluble in water. (d) Polar covalent compounds are good conductors of electricity.
