Question

When an organic compound containing Carbon, Hydrogen, and Nitrogen undergoes complete combustion with excess $CuO$ inside the heated combustion tube, which of the following gaseous species will exit the immediate combustion zone before passing over the hot copper gauze?

Prashant Kotian · Accepted Answer

Correct answer: A,B,C,D. Complete combustion with oxidizes carbon to and hydrogen to vapor. The nitrogen in the compound is mostly liberated as free gas. However, a fraction of the nitrogen may be oxidized to various oxides of nitrogen. All these gases pass down the tube. The subsequent heated copper gauze is specifically needed to reduce these oxides of nitrogen back to .
