Question

……………… is an example of triple covalent bond.

Answer 1

• Nitrogen has electronic configuration 2, 5. Its valence electron is 5.
• It needs 3 more electron to form stable configuration.
• So it shares 3 valence electrons with neighbouring nitrogen atom.
• The covalent bond formed by sharing of electrons is called covalent bond.
• Here nitrogen shares its 3 electrons and form triple covalent bond.

$:\mathrm{N}⋮+⋮\mathrm{N}:\to :\mathrm{N}⋮⋮\mathrm{N}:\mathrm{or}:\mathrm{N}\equiv \mathrm{N}:\mathrm{or}{\mathrm{N}}_2$
