Hello aspirant,

Covalent bonds are directional in nature as the bond prefers specific orientations in space relative to one another which results in molecules having definite shapes. Hence, they form bonds in a particular direction whereas in ionic bonds, each ion is surrounded by a number of oppositely charged ions and hence no definite direction and are not real bonds. Examples of compounds having covalent bond are CH4, CO etc. while compounds having ionic bond are NaCl, KCl.

Hope, this answer helps you.
