Question

Covalent compounds are generally soluble in:
A) Non-polar solvents.
B) Polar solvents.
C) Both A and B.
D) None of the above.

Answer 1

Hint: We know that the solubility of covalent compounds is determined by the polarity of the substance. Non-polar substance dissolves in non-polar solvents whereas highly polar compounds dissolve in highly polar solvents.

Complete step by step answer:
We must know that the covalent compounds are held tightly because the atoms in the covalent compounds have strong intramolecular bonds. Covalent compounds are less-polar so they are soluble in non-polar substances like ether.

$\therefore $The correct answer is an option (A).

Additional Information:
Let, we discuss some properties of covalent compounds.
1.A covalent compound is formed when two or more nonmetals by sharing the valence electrons.
2.Covalent bonds are the strongest chemical bonds which exist between atoms.
3.The energy of the bond is about $80\,kcal/mole$.
4.These bonds are directional where the atoms that are bonded show some specific orientation relative to one another.
5.Covalent compounds are the compounds with low boiling and melting points.
6.Covalent compounds do not conduct electricity.
7.Covalent compounds do not conduct heat since they lack electrons.
8.Covalent compounds are not soluble in water.

Note:
 Also we must know that water molecules have slight negative charge on the oxygen atom and positive charge on the hydrogen atom while covalent compounds are neutral molecules so covalent compounds do not dissolve in water. Sugar, carbon dioxide, and alcohols like methanol are covalent compounds but they dissolve in water but they do not dissociate into ions like ionic compounds.
