Question

Using the structure of the molecule and the IUPAC nomenclature rules, predict the name of the ternary molecule HCN. A) Hydrocyanic acid B) The two nonmetals indicate that covalent naming rules apply. C) The name of the anion predicts the name of the final molecule. D) The lack of oxygen in the anion indicates the prefix "hydro-" is used.

Answer 1

Hydrocyanic acid.

Step-by-step explanation:

Hydrocyanic acid or hydrogen cyanide is also known as formonitrile (HCN), it is a colorless, extremely poisonous liquid (because it inhibits cellular oxidative processes) which is having boiling point 26 °C, freezing point -14 °C, and highly volatile in nature.

The solution of hydrogen cyanide in aqueous is known as Prussic acid or Hydrocyanic acid. Hydrogen cyanide is used for many chemical processes such as fumigation, the concentration of ores, the case-hardening of steel and iron.
