CHEM 216 Lecture Notes - Lecture 4: Infrared Spectroscopy, Aldol Reaction, Acetophenone
Document Summary
Tabtila chowdhury: create a table below to concisely communicate the important results from your experiment (this may include important ir peaks, rf values by tlc, approximate reaction time, percent yield or anything else that you think is important). 4-nitrobenzaldehyde (we changed aldehydes in this experiment instead of ketones) 1 small oblong circle: rf value = 0. 88. Co-spot with aldehyde: one long circle: rf value = Longer circle didn"t appear in neither product nor aldehyde. Co-spot with ketone: no circle from the product, both were from ketone. Large circle rf = 0. 90 and smaller circle rf = 0. 62. Stir for 15 minutes once all the reagents were added and until a precipitate formed. (it stirred until the ppt. made it hard to stir any longer). Then, stirred for another 15 minutes after adding the ice water to the precipitate by breaking the precipitate and mixing it well with the ice water.
