What is the relationship between the chemical compounds HCN and NH3 in terms of their properties and reactivity?

Hydrogen cyanide (HCN) and ammonia (NH3) are both chemical compounds with different properties and reactivity. HCN is a toxic gas with a bitter almond odor, while NH3 is a pungent gas with a strong odor. HCN is a weak acid, while NH3 is a weak base. In terms of reactivity, HCN is more reactive than NH3 and can easily react with other compounds. NH3 is less reactive and tends to act as a nucleophile in reactions. Overall, the relationship between HCN and NH3 is that they have different properties and reactivity due to their chemical structures and compositions.
