  1. LABORATORY NOTEBOOK(Pre-lab) • OBJECTIVE (Must clearly state…) • What compounds you will make and how • How you will purify the compound • How you will determine the purity of your compound • CHEMICAL EQUATION • Include the general chemical equation from top of page 93. • TABLE OF PHYSICAL DATA (Single organized table, must include...) • LIQUIDS: (MW, bp, density, hazards) 2-methylcyclohexanol, Hydrobromic acid, sulfuric acid, 1-bromobutane, 2-bromobutane, 2-bromo-2-methylpropane, 1-bromo-1-methylcyclohexane (no bp/density required), and 1-bromo-2-methylcyclohexane (no bp/density required). • REFERENCE TO PROCEDURE (Must include…) • full title • Edition • authors • page numbers where actual procedure can be found

  2. LABORATORY NOTEBOOK(In-lab) • DATA/CALCULATIONS • Initial weight of 2-methylcyclohexanol used • Initial 50 mL beaker weight • Final 50 mL beaker weight • Final product weight • Physical state and color of product • Theoretical yield calculation (not just the number!) • Percent yield calculation (not just the number!) • EXPERIMENTAL PROCEDURE • In paragraph form, describe the procedure that you actually followed during the lab. • Paragraph must be written in PAST TENSE, PASSIVE VOICE. • Include ACTUAL volumes or weights of chemicals used during the experiment. • Include any mistakes, accidents, or observations if necessary.
