Vedclass · Answer

(A) Carbon monoxide $(CO)$ burns with a characteristic blue flame in the presence of oxygen to form carbon dioxide $(CO_2)$. The reaction is: $2CO(g) + O_2(g) \rightarrow 2CO_2(g)$. Hydrogen $(H_2)$ also burns with a pale blue flame,but in the context of $p$-block elements chemistry,$CO$ is the classic example associated with this property.
