Which of the following is drawback of the octet theory?I. It is clear that octet rule is based upon the chemical inertness of noble gases. However, Some noble gases (for$$ example xenon and $$krypton) also combine with oxygen and fluorine to form a number of compounds like $$XeF2$$,$$KrF2$$,$$XeOF2$$ etc. II. This theory does not account for the shape of molecules.III. It does not explain the relative stability of the molecules being totally silent about energy of a molecule.Choose the correct option.

Infinity Learn · Accepted Answer

Drawbacks of octet $$rule(i)$$ Elements like Xe, Kr has complete octet, it undergoes chemical combination with highly electronegative O and F both.(i) This theory never say anything about structure of molecule.(iii) This theory does not deal about energy of various possible structures.
