3168‚ Australia Received 13 October 1998; received in revised form 22 December 1998; accepted 23 December 1998 Abstract The oxidation products of cyclohexene "nd several applications as intermediates for the manufacture of useful chemicals like cyclohexanol‚ cyclohexenol/cyclohexenone‚ cyclohexadiene‚ etc. The uncatalysed oxidation of cyclohexene with molecular oxygen was studied in a batch reactor. The products‚ cyclohexene hydroperoxide‚ cyclohexenol‚ cyclohexenone and cyclohexene oxide were realised

Notes Aldehydes and Ketones The major similarity between an aldehyde and a ketone is the carbonyl group. A carbonyl group is a carbon atom doubly bonded to an oxygen atom. [pic] Both molecules have a carbonyl group‚ the difference the number of carbons bonded to the carbonyl carbon. An aldehyde will have none or one and a ketone will have two carbons. All aldehydes‚ except formaldehyde‚ will have a hydrogen atom on one side of the carbonyl carbon and at least on carbon on the other side

Abstract Introduction The acylation of the α carbon position of a carbonyl group is one of the greatest breakthroughs that has benefited chemists in organic synthesis particularly when in need of building a carbon skeleton of interest in a molecule. For one to be able perform this acylation technique‚ there are two mar approaches which are employable. The first method involves the deprotonation of the α-Carbon atom which has a pKa known to be ̴20 through the use of a strong base for instance

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

Phenomenon of new drugs on the Internet: the case of ketamine derivative methoxetamine On the basis of the material available both in the scientific literature and on the web‚ this paper aims to provide a pharmacological‚ chemical and behavioural overview of the novel compound methoxetamine. This is a dissociative drug related to ketamine‚ with a much longer duration of action and intensity of effects. A critical discussion of the availability of information on the web of methoxetamine as a

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

by : Directorate of Education‚ Delhi SOME IMPORTANT REASONING BASED QUESTIONS OF ORGANIC CHEMISTRY 1. Chlorobenzene is less reactive than chloromethane. Ans. In chlorobenzene‚ each carbon atom of benzenering is sp2 hyridised and is electron withdrawing. Chlorine atom donates a lone pair of electron and acquire positive charge. The negative charge is delocalised on ortho and para position by resonance. C-Cl bond acquires partial double bond character and is 169 pm as compared to 17.0 pm in chloromethane

Analysis of an Unknown Mixture Performed: 2/13/14 Submitted: 3/3/14 Abstract: The purpose of this experiment was to separate and identify the two unknown compounds. The sample used was 105 and it contain 2-propanol and 2-heptanone. IR spectrums were taken of the contents of the second and sixth test tubes and showed the presence of an OH functional group and a small amount of ketone in test tube two and a large presence of ketone in test tube six. The average boiling points of the test tubes
