Nitrogen compounds — practice question

Methylamine, $\text{CH}_3\text{NH}_2$, has chemical properties that are very similar to those of ammonia, $\text{NH}_3$. When methylamine reacts with hydrogen chloride, a white crystalline salt called methylammonium chloride is produced. $\text{CH}_3\text{NH}_2 + \text{HCl} \rightarrow \text{CH}_3\text{NH}_3^+\text{Cl}^-$ A sample of methylammonium chloride is warmed with aqueous sodium hydroxide. Which products are formed?

  • Aammonia, sodium chloride and water
  • Bammonia, sodium hydrogencarbonate and sodium chloride
  • Cmethylamine, hydrogen chloride and water
  • Dmethylamine, sodium chloride and water
