B F F F C F H F F H 3 C-CH 2 -C-O-H O H-C-O-H H H Problem Set 1 Molecules Answer all of the following questions and turn in to your laboratory instructor 1. Use the following electronegativity values to answer the questions below: i. Indicate whether each molecule is polar or non-polar (a through f, ½ pt each): a. Non polar b. Polar c. Polar___________ d. Non polar e . Polar f. Polar____________ ii. Briefly explain how you determined the polarity of each molecule (½ pt each): a: This molecule’s electronegativity was less than 1, and is physically symmetrical. b: This molecule’s electronegativity was 1.5 and its physical shape was not symmetrical. c: This molecule’s electronegativity was 2 and its physical shape was not symmetrical. d: This molecule’s electronegativity was .4, and is physically symmetrical. e: This molecule’s electronegativity was equal to 1.5, and it is not physically symmetrical. f: This molecule’s electronegativity was equal to 1.4 and its physical shape was not symmetrical.
