1. Naming Binary Compounds 1.Use prefixes then name element 2.Don’t use mono-for first element 3.Change ending of 2 nd element to – ide H 2 O dihydrogen monoxide NH 3 nitrogen trihydride N 2 H 4 dinitrogen tetrahydride C 5 H 10 pentacarbon decahydride 1 = mono 2 = di 3 = tri 4 = tetra 5 = penta 6 = hexa 7 = hepta 8 = octa 9 = nona 10 = deca

2. H 2 O CCl 4 As 2 O 3 SO 2 H 2 O 2 NH 3 N 2 H 4 N 2 O P 10 O 4 N 5 O 9 Naming Binary Covalent Compounds VI

3. Naming Binary Acids (H Element) 1.To name hydrogen use hydro- 2.Use the root word of the element and change ending to –ic acid HS hydrosulfuric acid HBr hydrobromic acid HCl hydrochloric acid HI hydroiodic acid

4. Naming Ternary Acids (H Element Element) Don’t use hydro 1.Use anion name and acid 2.If anion ends in –ate change it to –ic acid 3.If anion ends in –ite change it to –ous acid HClO 3 (ClO 3 = chlorate)chloric acid HClO 2 (ClO 2 = chlorite)chlorous acid

5. Molecular Formulas Practice V 1.H 2 SO 4 2.HCl 3.H 3 PO 4 4.HClO 2 5.H 2 SO 3 6.HF 7.HNO 2 8.O 2 9.H 2 10.Br 2
