MCQs on Chemical Bonding and Molecular Structure for NEET

Except for noble gases, no other elements occur independently. The attractive force by which atoms, ions and molecules are held together is known as a chemical bond. The atom has a tendency to gain stability by completing their octet. Oppositely charged ions are held together by an ionic bond. In a covalent bond electron pairs are shared. Molecules are held together by weak Van der Waal’s interaction in a crystalline structure.
