What are the rules for naming covalent bonds?

1. name the first element then the second using its root+ide (indicate prefixes if applicable) ex. CO2 carbon dioxide


NO nitrogen monoxide, etc





2. for acids containing hydrogen (except in gaseous forms) hydro + the suffix -ic is attached to the root then added acid in the end. ex. HCl hydrochloric acid, H2SO4 sulfuric acid H2SO3 sulfrous acid. if gaseous, it is named the same way as number 1. example, HBr (g) is hydrogen bromide. for halides containing oxygen, it is dependent upon the number of oxygens attached to it. example, HClO is hypochloric acid, HClO2 is chlorous acid, HClO3 is chloric acid, HClO4 is perchloric acid. strong acids are named with the suffix -ic and weak acids with -ous.





3. bases containing OH are named the same as number 1 but hydroxide is attached in the end for the OH.





research more on rootwords of elements and compunds to help you with nomenclature. especially with complex compounds. example CN- is cyanide, SCN- is thiocyanide, etc.
