Reply: Bond buy is defined as the fifty percent with the distinction between the amount of electrons current in bonding and antibonding molecular orbitals.
Due to two lone pairs of electrons on O-atom, repulsion on bond pairs is larger in H20 in comparison to NH3 . Consequently, the bond angle is less in H20 molecules.
(b)The best rise in ionization enthalpy is skilled on removal of electrons from Main noble gasoline configuration.
Concern 34. Compose the important problems required for that linear mixture of atomic orbitals to sort molecular orbitals.
A a number of bond is taken care of as if it is solitary bond as well as remaining electron pairs which represent the bond may very well be regarded as solitary Tremendous pair.
