may have caused poor purity‚ of which include reaction incompletion during exposure to microwave radiation‚ poor mixing‚ and poor product isolation during column chromatography. As seen in the 1H NMR spectrum‚ impurity peaks (>10%) corresponding to methyl (triphenylphosphoranylidene) acetate‚ acetone‚ ethyl acetate‚ and hexane were identified. The phosphonium ylide peak indicates that the reaction did not go to completion (leftover starting material). Meanwhile‚ the acetone‚ ethyl acetate‚ and hexane

Functional Groups of Organic Compounds A functional group is a specific arrangement of atoms in the HC derivative other than carbon and hydrogen. Literally‚ the functional group determines the functions of the particular HC derivative in chemical reactions. This means that the specific properties of the HC derivative are due to its functional group. Each functional group is attached to an alkyl radical (R). An alkyl radical is one H atom less than the given alkane. The alkyl radical (R) uses

nitronium ion. Electrophilic aromatic substitution is a method used when a functional group is needed to be substituted on to an aromatic compound. In the nitration‚ nitronium ion acts as the electrophile that involves the attack of the electron-rich benzene ring. Aromatic substitution is electrophilic‚ due to the high density in benzene ring. Benzene ring is one of the components in most important natural products and other useful products. The species reacting with the aromatic ring is usually

Title: Acetanilide Synthesis Objective: To synthesize Acetanilide by recrystallization. To check its purity by calculating its percent yield. Introduction: Aniline is a primary aromatic amine and weak base which forms salts with mineral acids. In acidic solution‚ nitrous acid converts aniline into a diazonium salt that is an intermediate in the preparation of a great number of dyes and other organic compounds of commercial interest. When aniline is heated

SYNTHESIS OF 1-PHENYLAZO-2-NAPHTHOL ABSTRACT Amines are compounds composed of nitrogen atoms bearing alkyl or aromatic compounds. Amines undergo interesting reactions‚ one of which is with the reaction with nitrous acid producing an azo dye. In this study‚ the experiment focused on synthesizing an observing the physical properties of Sudan-1. Sudan-1 is of the most common dyes found in waxes‚ oils and in some food ingredients specifically curry and chilli powder. Furthermore‚ this study aimed to
