Maleic acid and fumaric acid lab report

Experiment 1 Laboratory Safety and Intermolecular Forces Prelab Responsibilities • • Review Experiment 1. You will receive a set of molecules. Determine the molecular shapes and polarity of the molecules BEFORE your first lab (see Part A in Procedure part, p. 5). Review the appropriate material in chapter 10 of your textbook. General Information • • • • • • • The data sheet will become available for downloading on UM Learn at the beginning of the lab session. To locate it, go to Content > Experiment 1 > Data Sheet Experiment #1. Throughout the lab session you will be assigned to Break-out rooms to work on the questions. You are encouraged to consult other students. The data sheet is due at the end of this lab session. You will receive an email from Crowdmark at the beginning of the lab. Submit your data sheet following this link. You will be marked on the quality of the observations in your data sheets and on the answers to the questions provided. No formal report is required. You must always thoroughly record all data and observations in your data sheets in ink. Your writing must be clear and legible. Writing that is too light to read or is illegible will receive no credit. Fabricating data or copying data or text from another student is an act of academic misconduct. The minimum penalty for a first offence is a grade of zero, with more serious consequences for subsequent offences. Objectives 1. To learn how to work safely in a Chemistry laboratory. 2. To demonstrate and explain the impact of the intermolecular forces on the properties of the diverse materials. Part 1: Laboratory Safety Introduction One of the objectives of this laboratory session will be to introduce standard safe laboratory practices and to raise your awareness of the hazards and potential risks present when working in a chemical environment, i.e. a workplace where controlled products are used. Controlled products include laboratory chemicals, solvents, fuels, food additives, chemicals used in manufacturing, cleaners, and pharmaceutical products. Clearly, chemical environments are not limited to university chemistry laboratories; engineers, medical professionals, technicians, scientific researchers, product designers, mechanics, and numerous others regularly work in a chemical environment. Chemicals and procedures have an inherent level of hazard that poses an associated risk of injury. While hazards cannot be changed, risk can be reduced through the employment of safe laboratory practices. Good planning and safety-consciousness reduces the likelihood of accidents. Nevertheless, accidents do happen, so it is important that you know how to respond to them appropriately and expediently. During this laboratory session your TA will guide you through a number of safety-related exercises, including: • • an introduction demonstration of the safety equipment Part 2: Intermolecular Forces Experimental Question • How can certain physical properties point to the strength of intermolecular forces?

These forces are called Intermolecular Forces (IMF). They comprise dispersion forces, dipolar forces, and hydrogen bonding. IMF are responsible for many of the physical properties of the substances. A number of parameters is a good indicator of the strength of these attractive forces such as enthalpy of vaporization, boiling and melting points, solubility, and viscosity. In this experiment, you will explore the relationship between the intermolecular forces and some of these properties.
