Question

Choose the correct options regarding the type of covalent bond formed in the given elements and compounds.

• A. Nitrogen - Triple bond
• B. Oxygen - Double bond
• C. Hydrogen chloride - Single bond
• D. Lithium chloride - Single bond

Answer 1

Answer: (A), (B), (C)

The correct options are
A Nitrogen - Triple bond
B Oxygen - Double bond
C Hydrogen chloride - Single 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.
