Vedclass · Answer

(D) The octet rule states that atoms tend to form bonds such that they have $8$ electrons in their valence shell. In $CO_2$,carbon has $8$ electrons and oxygen has $8$ electrons. In $H_2O$,oxygen has $8$ electrons and hydrogen has $2$ electrons (duplet rule). In $O_2$,both oxygen atoms have $8$ electrons. In $CO$,carbon has $6$ electrons and oxygen has $8$ electrons. Since carbon in $CO$ has only $6$ electrons,it does not obey the octet rule.
