Question

The covalent compound is soluble in:
A. Polar solvent
B. Non-polar solvent
C. Concentrated acid
D. All solvent

Answer 1

Solubility is defined as the maximum amount of solute in gram dissolved in a given amount of solvent to form a saturated solution at a given temperature. Or we can say solubility is the tendency of any solute to dissolve in the solvent.

Complete step by step answer: The solubility of any substance depends upon the nature of the solute and solvent. In general, solute dissolves solvent which is chemically similar to it. This is expressed by ‘Like dissolve like’ rule and it states that polar solute dissolves in a polar solvent and less soluble or insoluble in a nonpolar solvent. Whereas the non-polar solute dissolves in a nonpolar solvent and less soluble or insoluble in a polar solvent.
Covalent compounds are formed using covalent bonds that involve the sharing of one or more pairs of valence electrons and they are non-polar, so generally, we can say Covalent compounds are soluble in Non-Polar solvent.
So, the correct answer is “Option B”.

Additional Information: Solubility of covalent bonds is very useful in the pharmaceutical industry and if a medicine is not soluble in water then it will be insoluble in the bloodstream and won’t reach the required site on time. Also, vitamin B and C are water-soluble whereas A, D, E, and K are oil/Fat-soluble.

Note: Solubility is different for different compounds in different phases and usually occurs under dynamic equilibrium. It involves two simultaneously occurring processes: dissolution and precipitation and these processes occur at the same rate. Covalent compounds that dissolve in water break into smaller molecules unlike the case of ionic compounds that break into ions when they dissolve.
