Question

The class of compounds that utilize the prefix system when naming are known as

Select one:

a. metallic compounds

b. polyatomic compounds

c. covalent compounds

d. ionic compounds

Answer 1

Prefix = anything that goes BEFORE

therefore, this can't be ionic, since ionic compounds has SUFFIX, which are AFTER the name

ignore d

metallic compounds will always be named as their elements, so ignore a

only options are b and c

NOTE: most polyatomic compounds are covalent compounds, but this is not the general case

so

the best answer is POLYATOMIC COMPOUNDS

such as:

HClO4 = perchloric acid, per states most oxidized state

permanganate ion --> most oxidized state of Manganese, i.e. Mn+8

etc...
