Naming acids covalent/molecular compounds Ch. 2 in book

Rules for naming acids 1. Binary Acid (like a simple ionic cpd) Prefix hydro + nonmetal root + suffix -ic + (separate word) acid Ex) HCl = hydro + chlor + ic + acid = hydrochloric acid 2. Oxoacid (like naming with oxoanions but…) -ate becomes -ic in the acid -ite becomes -ous in acid Ex) HBrO 4 is perbromic acid

Acids practice HBr HIO 3 HCN HNO 3 Hydrobromic acid Iodic acid Hydrocyanic acid Nitric acid

Rules for naming molecules Two nonmetals: 1.Lower group number 1st-except oxygen and halogen-halogen 1st 2.If in same group higher period 1st 3.2nd element named root with -ide 4.USE GREEK! Greek prefixes for how much of each compound- 1st number only needs if +1

Greek prefixes 1-mono 2-di 3-tri 4-tetra 5-penta 6-hexa 7-hepta 8-octa 9-nona 10-deca

Molecules practice PCl 5 Formula for carbon disulfide Name and formula for cpd with 2-N and 4-O Phosphorus pentachloride CS 2 Dinitrogen tetraoxide –N 2 O 4

If there is a hydrogen in the middle… Example) NaHCO 3 How would you name it otherwise? –Ionic: m/PAI Same but add hydrogen (use prefix if +1) Name: sodium hydrogen carbonate Practice: KH 2 PO 4 Potassium dihydrogen phosphate
