The correct option is D Nitrogen - Triple bond
- A covalent bond is formed by mutual sharing of electrons between the atoms of the molecule.
- In nitrogen, three pairs of electrons are shared between the two nitrogen atoms resulting in the formation of a triple covalent bond.
- In oxygen, two pairs of electrons are shared between the two oxygen atoms resulting in the formation of a double covalent bond.
- In hydrogen chloride, one pair of electrons is shared between the hydrogen and chlorine atoms resulting in the formation of a single covalent bond.
- Lithium chloride is an ionic compound.
