Question

explain the intermolecular forces and bonding?

within one molecule

between multiple molecules

Answer 1

Intermolecular forces are the forces which deal interaction between molecules, including forces of attraction or repulsion which act between molecules and other types of neighboring particles, e.g., atoms or ions. They are of diiferent types.

Hydrogen bond is one type of inermolecular force.

Example: In water each molecule is attractedd to two other water molecules by hydrogen bonding. This may be termed as one form of intermolecular force. Water molecules have a permanent dipole moment due to which there exists a partial positive charge on both the hydrogens and a partial negative charge on thee oxygen atoms. The hydrogen atoms from two other water molecules get attracted to the oxygen atom of one water molecule there by forming hydrogen bonds.

Bond is something that is formed between two atoms of the same molecule either by exchange or sharing electrons. This is very different from intermolecular forces. A bond is way more stronger than intermolecular forces.

Example: In H₂O molecule each hydrogen and oxygen atom share a pair of electrons. This sharing of electrons is said to be a bond.
