Which of the following formulae does not show the correct relationship?
Formula for finding B.O is;
Bond order=0.5(Nb–Na) or
B.O=Nb−Na2
The bond order is the number of electron pairs joint between two atoms in bond making.
When the maximum number of electrons joint between two atoms, the stronger the bond and more dissociation energy is required to break the bond. The amount of energy needed to break a bond is called bond dissociation energy or simply bond energy. The larger the bond energy, the bond will stronger. So, Bond energy is directly proportional to bond dissociation energy.
Always first Bonding gets filled first followed by the filling of anti-bonding. So Nb is always >Na.
The correct answer is Option C.
