Here's why:

* Covalent compounds are formed when atoms share electrons to achieve a stable electron configuration.

* Ionic compounds are formed when atoms transfer electrons, resulting in the formation of positively charged ions (cations) and negatively charged ions (anions) which are then held together by electrostatic attraction.

Isopropyl alcohol (C3H8O) consists of carbon, hydrogen, and oxygen atoms. These atoms share electrons to form covalent bonds within the molecule.

While surgical spirit may contain other ingredients like water and small amounts of other chemicals, the primary component, isopropyl alcohol, is a covalent compound.
