Our Infrared Spectroscopy (IR) spectrum for our Acetaminophen KBr pellet provided a handful of strong peaks and hints that helped us to hypothesize what functional groups might be in Acetaminophen. The peaks that were at the highest wavenumbers were analyzed first. The strong peak at 3325.82 cm-1 was an indicator that there was stretching occurring between a Hydrogen and Nitrogen atom. This signified that Acetaminophen could contain an amide group. The next defined peak is located at 3162.26 cm-1

out of the solution can be seen in the IR graphs for each substance. For ethyl 4-aminobenzoate‚ the N-H‚ C=O and C-O are distinguishable in their proper wavenumber positions. The amino N-H stretch was found between 3224 cm-1 and 3423 cm-1. The C=O was found at 1681 cm-1 and the C-O was at 1280 cm-1. The IR for benzoic acid also displays its significant bonds‚ O-H and C=O. The O-H was between 2566 and 3222 cm-1 and the C=O stretch was found at 1685 cm-1. The IR for 9-fluorenone did not show any significant

passed by congress in 1982‚ when the Internal Revenue Department brought a case against a convicted cocaine trafficker. The trafficker in reply to the IRS‚ filed a return where he claimed deductions for objects used to traffic said drugs (i.e. the guns bought for protection ect.) Being that no regulations were put into place to combat this issue‚ the IRS was required to accept the returns. As a result of this‚ the trafficker was allowed to keep over half of his earnings.

Aldol In this preparative lab‚ an aldol (trans-p-anisalacetophenone) was produced from the reaction between p-anisaldehyde and acetophenone with the presence sodium hydroxide. The reaction also showed the importance of an enolate and the role it played in the mechanism. Sodium hydroxide acts as a catalyst in this experiment and is chosen because of its basic conditions and pH. The acetophenone carries an alpha hydrogen that has a pKa between 18 and 20. This alpha hydrogen is acidic because of its
