PAL— Nomenclature Review Part I: Types of Compounds 1. Put a check in the box for the appropriate class/subclass for each of the following compounds. Use the ﬂowchart in ﬁgure 5.17 (and the back of these worksheets) to name the compound. The same ﬁgure can also be found at the back of this worksheet. Each subclass has its own rules for naming. Chemical Formula Ionic, Type I Ionic, Type II Molecular Acid, Binary Acid, Oxyacid Compound Name CCl4 SnCl2 HCl (aq) SrCl2 NH4Cl H2CO3 (aq) MgCO3 (aq) MnCO3 CO2 H2 S NaBr 1 2. We can also use the ﬂowchart to from name à formula. Provide the class/subclass and formula for each of the following compounds. Chemical Name Class/subclass Compound Formula Hydrosulfuric Acid Sulfuric Acid Sulfurous Acid Sulfur Dioxide Hydrophosphoric Acid Phosphoric Acid Phosphorous Acid Tin (IV) Sulﬁte Cesium Sulfate Silver Sulﬁde Nitrogen Dioxide Sulfur Tetroxide Hydroiodic Acid 2 Part II: At Home Practice You are likely expected to know the names, symbols, and formulae for at least 50 elements and ions. That’s over 1000 possible compounds that can come from the combinations possible! This is impossible to memorize. Instead, focus on memorizing the required ions and elements. This exercise is one way that you can start to learn and understand the rules behind nomenclature of ionic compounds. • For each ion write the name on one side of the ion and the symbol or formula on the other side. • Make two piles of ions. One pile will be positively charged ions (cations) and the other will be negatively charged ions (anions). • Shu[le both piles. Make sure all the cards are still facing the same direction (name up and symbol down or vis versa) • Use the top card of each deck to randomly “create” an ionic compound. If the cards are name up, determine the formula of the compound. If the cards are symbol up, determine the name. • Repeat until you’ve pulled all of the cards from one stack. • Shu[le each deck and start over! 3 4
