Verified step by step guidance1
Identify the components of the compound HCN. It consists of hydrogen (H), carbon (C), and nitrogen (N).
Recognize that HCN is a binary acid, which typically consists of hydrogen and one other non-metal element.
Understand that binary acids are named using the prefix 'hydro-' followed by the root of the non-metal element's name and the suffix '-ic'.
Determine the root name for the non-metal element in HCN, which is 'cyan' derived from the cyanide ion (CN⁻).
Combine the prefix 'hydro-', the root 'cyan', and the suffix '-ic' to form the systematic name 'hydrocyanic acid'.
