Intramolecular and Intermolecular Bonds

Intramolecular Bonds:
In any given molecule, the atoms interact with each other via intramolecular bonds.

  • 1. Covalent Bonds: 
  • These are the bonds that hold the atoms together in a molecule. 
  • These are the strong bonds that cannot be broken except for by the enzymatic actions. 
  • There are two types of covalent bonds:

1.1. Non-Polar Covalent Bonds: 

  • These bonds are formed when two atoms share electrons equally such that their electronegativity value is also equal. For example, H2:

 

1.2. Polar Covalent Bonds: 

  • Due to the difference in the electronegative values of the atoms, the sharing of electrons become unequal. 

  • The bond formed due to an unequal sharing is called a polar covalent bond. 

  • Herein, one atom is partially electronegative and the other partially electropositive. 

  • For example,  H2O
