alcohol with concentrated hydrochloric acid. Q6. Explain why the solution became milky white in appearance after adding 11 M HCl(aq) to the tertiary butyl alcohol. Q7. A student is given two alcohols with which to perform Lucas Test. These are cyclohexanol and 2-methyl-2-propanol. The bottles containing each alcohol are labelled‚ but the propettes used are not. The student accidentally muddles the propettes. When drops of each alcohol are mixed with Lucas. Reagent and kept at 27 °C‚ both solutions

product: C) Acetophenone = contains alpha hydrogen‚ aldol condensation product: D) Formaldehyde has no alpha hydrogen so aldol condensation is not possible. E) Benzophenone has no alpha hydrogen so aldol condensation is not possible. F) Cyclohexanone = contains alpha hydrogen‚ aldol condensation product: 4. Ketones are less reactive than aldehydes in aldol condensations because the carbonyl group on the ketone is more sterically hindered than the carbonyl group on the aldehyde. This sterical

125mL Erlenmeyer flask it contained 20.0 mL of deionized water and 20mL of concentrated sulfuric acid was added carefully with some swirling in between. The diluted acid was cooled with an ice water bath to 20-25ºC. to the cooled sulfuric acid cyclohexanol was added carefully and slowly with swirling as well. The reaction mixture cooled 65% sulfuric acid was transferred to the 100mL round-bottomed flask through a glass funnel‚ three boiling stones were added to the mixture and the distillation started

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

C H A P T E R 5 Basic Concepts from Organic Chemistry 5.1 | INTRODUCTION The fundamental information that environmental engineers and scientists need concerning organic chemistry differs considerably from that which the organic chemist requires. This difference is due to the fact that chemists are concerned principally with the synthesis of compounds‚ whereas environmental engineers and scientists are concerned‚ in the main‚ with how the organic compounds in liquid‚ solid‚ and gaseous wastes

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
