  MOLECULAR ORBITAL THEORY:     Introduction Salient features of MOT Types of bonding Bonding  Antibonding Difference Between bonding  Linear Combination of atomic orbital  a. INTODRUCTION:          THE MOLECULAR ORBITAL THEORY put forward by F.HUND and S.MULLIKEN developed a bonding theory to overcome the limitation of valence bond theory  and explain the magnetic behaviour of molecules. b. SALIENT FEATURES OF MOT : ¢   When atoms combines to form molecules, their individual atomic orbitals lose their identity and forms new orbitals called molecular orbital.  ¢   The electrons in a molecule are accommodated in the newly formed molecular orbitals.  The filling of electrons in these orbitals follows AUFBAU’S and HUND’S rule as the as in the case of filling of electrons in atomic orbitals.  ¢   The shape of molecular orbitals depends upon the shape of combining atomic orbitals.  ¢   The...

TYPES OF BOND

  TYPES OF BOND:   I ntroduction Single bond Double bond Triple Bond INTRODUCTION: The mutual sharing of one or more pairs of electrons between two combining atom result in the formation of a chemical bond called a covalent bond. Based upon sharing the pairs of electrons, the bond are classified into many types.      Single Bond       Double Bond   Triple Bond i.  SINGLE BOND:   If two atoms share just a pair of electrons , a single bond is formed.          Eample:    H 2     ii. DOUBLE BOND:         If two atoms share two pair of electrons , a double bond is formed.                         Example:        O 2    iii. TRIPLE BOND:      If two atoms share three pair of electrons , a triple bond is formed.             ...
