What is a covalent bond? Give one example each of a single, a double and a triple covalent bond.
Original Khojo Papers practice question — not from a past board paper.
Answer
A covalent bond is formed by the mutual sharing of one or more pairs of electrons between two atoms, so that each attains a stable outer shell. A single bond is found in hydrogen (H–H), a double bond in oxygen (O=O) and a triple bond in nitrogen (N≡N).
