Grinnell College‚ Grinnell‚ Iowa 50112‚ United States S Supporting Information * ABSTRACT: A simple organic chemistry experiment is described that investigates the kinetics of the reaction between 1-bromobutane (BuBr) and iodide (I−) as followed by observing the disappearance of BuBr and the appearance of 1-iodobutane (BuI) using 1H NMR spectroscopy. In small groups of three to four‚ students acquire data to examine the concentrationdependence of both the organic substrate and the nucleophile under

JANE ESTARIJA bs-biology MW 1:00 - 2:30 & 3:00 – 6:00 A carboxylic acid is an organic acid characterized by the presence of at least one carboxyl group. The general formula of a carboxylic acid is R-COOH‚ where R is some monovalent functional group. A carboxyl group (or carboxy) is a functional group consisting of a carbonyl (RR’C=O) and a hydroxyl (R-O-H)‚ which has the formula -C(=O)OH‚ usually written as -COOH or -CO2H. Carboxylic acids are Brønsted-Lowry acids because they are proton (H+)

higher resolution and more light‚ you need to put more than one mirror together and make them work together‚” explains Robert Angel‚ a professor of astrology at the University of Arizona (Giant Mirrors to Capture the Universe). Just as we learned in our lab‚ we need a good source of light for something to become clear. The mirrors that are used for the telescope cause the light to be reflected off of one mirror onto the other which then create a clear image from the large convex lens. “Because these
