Which of the following is a suboxide
1 \(B{a_2}O\)
2 \(CaC{O_3}\)
3 \({C_3}{O_2}\)
4 \(ZnO\)
Explanation:
Carbon suboxide, is also called as tricarbon dioxide, is an oxide of carbon with chemical formula \(C _3 O _2\) or \(O = C = C = C = O\). Its four double bonds make it a cumulene. It is one of the stable members of the series of linear oxocarbons
