Conversion of Alcohols to Alkyl Halides Title: Conversion of Alcohols to Alkyl Halides Abstract: In this experiment the conversion of alcohols to alkyl halides are investigated through reflux and simple distillation. These are common procedures used to separate substances. After the reflux and distillation is complete 13C NMR and IR spectrum is used to identify the product or products for each reaction: 1a‚ 1b‚ and 2. Every individual in the group was assigned either 1a (1-propanol) or 1b (2-pentanol)

interaction in absorbers‚ for instance the use of nanostructures like nanowires where leaky mode resonances enhanced absorption efficiency. Towards this goal‚ we present a study of the light absorption in single Si nanowires‚ by means of microphotocurrent spectroscopy combined with transport measurements of carrier diffusion length using the electron beam induced current technique. The study is performed on different diameter nanowires with Schottky junctions created by doping modulation during Chemical Vapor

Introduction: Oxidation involves the gain of electrons of hydrogen or the loss of oxygen or decrease in oxidation state. If zinc completely reacts with HCL‚ then the theoretical yield of copper should be equivalent to the actual yield. Purpose: In this lab‚ we will determine the percent composition of a modern (post-1982) penny by using a strong acid to react and dissolve the zinc core‚ leaving only the copper coating. Once only copper remains‚ we will compare its mass to the entire mass of the penny

ACKNOWLEDGEMENTS It is usually said that no man is an island unto himself‚ and any man who so lives all by himself‚ without interacting with his fellow men is in the words of Aristotle‚ “either a beast or a god”. Mutual co-operation and interaction form the cardinal feature of human life. The task of writing this report has not‚ in the least‚ been an easy one‚ and it would be axiomatic to add that all the numerous tasks involved could not be have been accomplished successfully singly
