What are molecular orbitals? How are they formed?What does molecular orbital theory states? what is the significance of molecular orbital theory?Ans) Molecular orbitals are formed when atomic orbitals of equal energy hybrize. MOT states that n no. of atomic orbitals hybridise to form n no. of molecular orbitals of equal energy. This theory helps us to give the arrangement of electrons in molecules and also its magnetic properties.
