| dc.description.abstract | This Thesis is a study of certain organic reactions with a view of adapting them to use in the laboratory instruction in a course in general Organic Chemistry. P:roject No.1, pages 1 thru 5, deals with the formation of a wide variety of azo coloring matters by diazotization, including a list of coloring matters which are recommended to the students as best bringing out this wide variety together with laboratory instruction for their formation. Project No. 2, pages 6 thru 10, deals with the conditions and time required, for the hydrolysis of an ester, e.g. n-butyl acetate and the identification of the products of the hyrolysis, together with procedures recommended to the students for such a hydrolysis and speedy but accurate proof of the products formed. Project No. 3, pages 11 and 12, deals with the reactiveity of the alkyl halogens when under the influence of activating groups, with a summary of the results obtained. Porject No. 4, pages 13 and 14, deals with the reactivity of aryl halogens when under the influence of nitro groups, with a list summarizing the results, and facts shown by the experiment, together with a procedure suggested for the conversion of 2-4 dinitro chloro benzene to 2-4 dinitroaniline by a test tube reaction. Project No. 5, page 15, which deals with the method for testing primary amines and amides by treating with nitrous acid, with evolution of nitrogen, with suggested procedure for the elimination of the difficulties brought about by the presence of the oxides of nitrogen. Project No. 6, page 16 and 17, which deals with the synthesis of n-butyl ethyl ether by use of ethyl sulphate instead of ethyl bromine, with summary of results obtained, and conditions which give best results, together with a suggested procedure for a test tube experiment illustrating this reaction. Project No. 7, pages 18 and 19, which deals with the effects of the substituents R & R' upon the rate of reaction of the ethylene compounds, as illustrated by the addition of bromine. A quantitative procedure by which this was studied is given, and a qualitative procedure by which the students may readily see the effect of various substituents is suggested.
