Verified step by step guidance

Understand the structure of cyanic acid. Cyanic acid is a simple compound consisting of hydrogen, oxygen, carbon, and nitrogen.

Identify the correct order of atoms in the formula. The typical order for writing chemical formulas is to start with hydrogen, followed by other elements in the order they appear in the compound.

Consider the connectivity of atoms. In cyanic acid, the hydrogen atom is bonded to the oxygen atom, which is then bonded to the carbon atom, and finally to the nitrogen atom.

Write the chemical formula based on the connectivity: Hydrogen (H) is bonded to Oxygen (O), which is bonded to Carbon (C), and then to Nitrogen (N).

The correct chemical formula for cyanic acid, based on the connectivity and order of atoms, is HOCN.
