Thanks for asking us a question in Ask the Expert section of TopperLearning.com.

Like dissolves like. Due to this compounds tend to dissolve in the other compounds that have similar properties (particularly polarity). Since water is a polar solvent and most covalent  compounds are nonpolar due to which they don't dissolve in water.
A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms. The stable balance of attractive and repulsive forces between atoms when they share electrons is known as covalent bonding.
For example. in a water molecule, each hydrogen atom (H) shares an electron with the oxygen atom (O).
