What is the correct Lewis structure for hydrocyanic acid (HCN) including the formal charges, if any?

Question

Quizplus · Accepted Answer

The correct Lewis structure for HCN is shown in Choice II. The central atom, carbon, has a triple bond with nitrogen and a single bond with hydrogen. Carbon has a formal charge of 0, nitrogen has a formal charge of 0, and hydrogen has a formal charge of +1. This is the best choice because it satisfies the octet rule for all atoms and gives the most stable arrangement of electrons.
