Type III Binary Compounds

Binary Molecular Compounds Two elements, usually nonmetals Familiar compounds use common names: NH 3 CH 4 H 2 O **most are named in a systematic way.

Monatomic Ions Ions formed from a single atom Written as (E 2+ ) or (E 2- ) Change ending to -ide.

Naming Acids and Covalent Compounds

Does it start with H? If so it is an acid Is it H + attached to a simple nonmetal ion? Then first word hydro- then simple ion then –ic ending, then acid If Anion is a polyatomic ion, then no hydro-, if ion ends in ate, use –ic, if ends in ite use –ide, then acid

HCl, (two elements, so start with hydro, chlorine becomes chlor-ic acid) HNO3 (polyatomic nitrate becomes nitr-ic. Nitric Acid) HNO2 ( polyatomic nitrite becomes nitr-ous . Nitrous acid)

Covalent naming If elements in a compound are all non metals, then we name using prefixes. We use greek prefixes: 1 mono- 4. tetra- 7 hepta- 2 di- 5 penta- 8 octa- 3 tri- 6. hexa- 9 nona-

exceptions If the first element is single, it does not need a mono-, but any subsequent will. If you are using oxide, you drop the last letter in multiple syllable prefixes. Mon-oxide (drop o) tetr-oxide (drop a)
