Question

What is the proper compound formula for Hydrogen Cyanide?

A.) H(CN)2
B.) H2(CN)
C.) HCN
D.) H2(CN2)

Answer 1

C

Step-by-step explanation:

Cyanide's formula can be found either on google on on a reference table at the "polyatomic ions" table. Hydrogen, H, has a charge of 1+ when bonded, and cyanide has a charge of 1- overall, so they will be in a one to one ratio while bonded. As such, the equation is HCN.
