A single molecule of ammonia reacts with a single molecule of ethyl methanoate, $\text{HCO}_2\text{C}_2\text{H}_5$, giving one molecule of methanamide, $\text{HCONH}_2$, together with just one further molecule, X. When one molecule of methanamide is strongly heated, it breaks down to form one molecule of ammonia and only one additional molecule, Y. What might X and Y be?
- Aethanoic acid; carbon monoxide
- Bethanoic acid; hydrogen cyanide
- Cethanol; carbon monoxide
- Dethanol; hydrogen cyanide
