Explanation / Answer

We Know that :      From the given compounds the onewhich doesn't obey octet rule is :        Chlorinetrifluoride ( ClF3 )    option C iscorrect.       The one which is not related tothe concept of the valence bond concept is :       Atomic orbitals on two atomsmay overlap to form antibonding orbitals.   option C is correct.       The element with highest firstelectron affinity is :         Sulphur      option D iscorrect.
