Premium Question Answer School terminology
Upon addition of bromine‚ the brown color of bromine quickly disappears as the bromine adds to the double bond in the products. Addition of bromine to the fractional distillate caused the bromine to discolor. The addition of bromine to 2-methyl-cyclohexanol remains brown because there is an absence of double bound (saturation). Addition of potassium permanganate caused the solution to turn slightly brown but appeared immiscible as result of the unsaturation product. When analyzing the IR results confirmed

Laboratory #6 Qualitative Tests for Carbonyls: Aldehydes vs. Ketones Introduction Various chemical tests identifying ketones and aldehydes are used in this experiment in order to identify an unknown carbonyl compound. The tests used are: 2‚4-dinitrophenylhydrazone test‚ Tollen’s Test‚ Benedict’s Test‚ Chromic Acid Test‚ aka Bordwell-Wellman Test‚ Schiff’s Test‚ and Iodoform Test. These classification tests provide results based on color change or formation of precipitation‚ which is then used

step involves the production of KA Oil (a mixture of cyclohexanone‚ the ketone and cyclohexanol‚ the alcohol component) and the second stage is its subsequent oxidation to adipic acid with an excess of strong nitric acid in the presence of copper and vanadium catalysts. Only 3-8 % conversion of cyclohexane is obtained in the first step. Recycling of the large amount of cyclohexane unreacted and separation of cyclohexanol and cyclohexanone from cyclohexane present major problems. In the second step the

BACHELOR OF SCIENCE (HONS) BIOTECHNOLOGY YEAR 1 SEMESTER 1‚ 2 & 3 UDBB 1164 FUNDAMENTAL ORGANIC CHEMISTRY 0 EXPERIMENT 1 PROPERTIES OF HYDROCARBONS Introduction Hydrocarbons are compounds which contain only carbon and hydrogen‚ can be classified into several types‚ depending on their structure. Aliphatic hydrocarbons are divided into three classes: alkanes (e.g. methane‚ ethane and propane) have only single bonds‚ and are said to be saturated; alkenes (e.g. ethene and propene)

peak at about 3300 in the IR corresponds to the O—H group in the product. The peaks to the right of aro0und 3000 are C—H related‚ those about 1599 are C—H bends‚ and the peaks at 1000-1350 are C—O related. The most plausible product seems to be cyclohexanol with a molecular formula of C6H12O. 2. Describe the stereochemical relationship between each pair of isomers. (a) Same

Katie Smith April 11‚ 2013 Competitive Nucleophiles Introduction The purpose of this experiment was to compare the nucleophilicities of chloride and bromide ions toward the n-butyl and t-pentyl alcohols. We were able to analyze this by using refractometry to measure the amounts of alkyl chloride and alkyl bromide in each reaction. Experiment Scheme (Procedure A) To begin the experiment‚ we assembled a reflux apparatus in the fume hood with a 100 mL round bottom flask and a condenser
