NAME _________ Quiz Section ___ Part I. Properties, Intra- and Inter- Molecular Forces and Structure of Maleic and Fumaric acids This report is due before you leave lab. You can talk with any of your fellow students about the work, but the TAs are not allowed to answer any questions about this part during the lab. Maleic acid and fumaric acid are stereoisomers of each other with the molecular formula C 4 H 4 O 4 or COOH-CH=CH-COOH. Maleic acid is the cis form and the trans form is fumaric acid. (See pg 949 of Zumdahl for explanations of cis and trans .) First draw the Lewis structures of each below. Maleic acid Fumaric acid Using the chemical model kit, make a model of each of the two structures and answer the following questions: 1. Which is able to form intramolecular hydrogen bonding? Draw the Lewis structure of this molecule and remember to use dotted lines for the intramolecular hydrogen bonding 2. If the substance forms intramolecular hydrogen bonding, the effect on the ability to form
