Important Questions from Chemical Bonding

1multiple correct

Which of the following compounds contain electrovalent bonds?

Show answer

NaCl, MgCl2, CaO

NaCl, MgCl2, and CaO are formed by electron transfer between metals and non-metals. H2O is formed by electron sharing (covalent bonding).

2multiple choice

Which molecule has a triple bond?

Show answer

N2

N2 (nitrogen molecule) has a triple bond where three pairs of electrons are shared between two nitrogen atoms.

3multiple choice

What is a lone pair of electrons?

Show answer

Electrons not involved in bonding

Lone pairs are valence electron pairs that are not shared with other atoms and remain localized on one atom.

4multiple correct

Which properties are characteristic of ionic compounds?

Show answer

High melting points, Conduct electricity in molten state, Soluble in water

Ionic compounds have high melting points due to strong electrostatic forces, conduct electricity when molten due to mobile ions, and are generally soluble in water.
