Question

Two non-metals A and B combine with each other by sharing of electron to form compound C. 

(i) What is the nature of compound C? 

(ii) Will it dissolve in water or organic solvents? Give reason for your answer.

Answer 1

(i) C is a covalent compound, as the combining atoms form a bond by sharing of electrons.

(ii) Using “like dissolves like” rule, polar molecules dissolve in polar solvents, whereas non-polar molecules dissolve in non-polar solvents. C and organic solvents are both covalent (non-polar) in nature, but water is a polar solvent. Hence C will dissolve in organic solvents.
