Introduction Friedel-Crafts acylation of anisole with acetic anhydride was used in this experiement to synthesize 4-methoxyacetophenone with the use of a reflux apparatus. Friedel-Crafts reactions can be done by alkylation‚ which involves mixing an alkyl or acyl halide with a Lewis acid‚ or acylation‚ which is done with acid chlorides or anhydrides(Lefevre). Acylation was used because it does not have as many disadvantages aklyations reactions have such as polyalkylation‚ second electrophilic attacks

system is to balance yourself. They believe that your body is self-correcting and self-perpetuating‚ like the universe itself. It mostly focuses on diet‚ yoga‚ and state of the mind‚ body‚ soul‚ and senses. The five elements of Ayurveda are space/ether‚ air‚ fire‚ water and earth.

essential oil of cloves are eugenol‚ eugenol acetate‚ and B-caryophyllene. Smaller amounts of compounds found in the essential oil of cloves are hydrocarbons‚ alcohol‚ phenol‚ ether‚ aldehyde‚ ketone‚ acid‚ and ester. Essential oils are volatile and have an odor. Essential oils are often flammable‚ soluble in alcohol and ether but partially soluble in water. The technique used was steam distillation. The steam distillation technique was used because it lowers the pressure in the flask so that it does

Your exam will be multiple choice Exam # 1 Introductory Chemistry Be sure to show your set up for all mathematical problems. Your answers must have the correct number of significant digits and the correct units. I. Chemistry is a quantitative science therefore we must make measurements. All measurements have an uncertainty that we need to be aware of in our calculations. A. We need to be able to determine the number of significant figures in a measurement. For the following measurement state the
