    Carbon sub-oxide \[\left( {{C}_{3}}{{O}_{2}} \right)\] has recently been shown as a component of the atmosphere of Venus. Which of the following formulation represents the correct ground state Lewis structure for carbon suboxide?

    A)  \[:O:C::C:C:O:\]           

    B)  \[:O::C::C:C::O:\]

    C)  \[:\overset{.\,\,.}{\mathop{O}}\,::C::C::C::\overset{.\,\,.\,}{\mathop{O}}\,:\]        

    D)  \[:O:C:C:C:O:\]

    Correct Answer: C

    Solution :

    \[:\overset{.\,\,.}{\mathop{O}}\,::C::C::C::\overset{.\,\,.}{\mathop{O}}\,:\] In structure [c], all the atoms have complete octet. Thus, it is the correct representation of carb sub-oxide.
