Question

Choose the correct options regarding the type of bonding in the following compounds.

• A. Hydrogen chloride- Ionic bond
• B. Magnesium oxide- Ionic bond
• C. Nitrogen- Covalent bond
• D. Hydrogen- Covalent bond

Answer 1

Answer: (B), (C), (D)

The correct options are
B Magnesium oxide- Ionic bond
C Nitrogen- Covalent bond
D Hydrogen- Covalent bond

Ionic bond is the bond formed by the transfer of electrons between the atoms. While covalent bond is formed by sharing the electrons between the atoms.

- In the formation of hydrogen chloride, hydrogen and chlorine atoms share one pair of electrons. So, a single covalent bond is formed.

- In nitrogen molecule, one nitrogen atom shares three electrons with another and forms a triple covalent bond.

-In hydrogen molecule, one hydrogen atom shares one electron with another and forms a single covalent bond.

- In magnesium oxide, magnesium transfers two electrons to oxygen to form an ionic bond between magnesium and oxygen.
