You should be able to: • Identify a compound using a chemical formula (Level 1-2) • Idenitfy an organic compound (Level 1-2) • Identify the elements in a compound (Level 1-2) • Decode a chemical formula (Level 3-4) • Describe why a compound is or is not organic. (Level 3-4) • Explain the connection between the chemical formula and the chemical bonded between the elements to make the compound (Level 5-6) Your Goals
Each compound has a chemical formula describing the elements bonded together • Methyl Bromide is a compound because it can be written using one chemical formula: CH3Br. • You need to be able to decode chemical formulas • Organic compounds contain carbon, C. • Methyl Bromide?? C H3 Br Bromine No number means 1 atom of bromine Carbon Hydrogen No number means 1 atom of carbon 3 hydrogen atoms Methyl Bromide (CH3Br) has 1 carbon atom, 3 hydrogen atoms, and 1 bromine atom Compound: methyl Bromide Methyl Bromide (CH3Br) is organic because the formula contains carbon
