(Hint: Other than cyclohexane‚ there are 11 ways to draw a six-carbon backbone that contains a ring. Plus there are isomers of cyclohexane that do not contain a ring.) (10 points) 3. Are any constitutional isomers missing from Column 3 in Model 1? A good way to answer this and similar questions is to start by drawing all

the sulfanilamide was dissolved in the mother liquor‚ and also because of a small spillage of the crystals from the filtration step. Part C of this lab was performed by first finding the best solvent for Fluorene. This was done by testing water‚ toluene‚ and methyl alcohol by adding 6mL of solvent to .3g of Fluorene. It is then shaken‚ if it dissolves immediately like it did

Infrared Spectroscopy Organic Chemistry Lab 301A B. The purpose of this lab is to study Infrared Spectroscopy‚ which focuses on the study of the electromagnetic spectrum. The area to be studied is the infrared region‚ which is made up of gamma‚ X‚ and UV rays. We want to be able to identify spectra’s to their complementary structures. The background of this experiment particularly deals with the study of compound structure determination‚ and traits. We must be aware of the functional groups

investigation along similar lines to the work you did on the chlorides of the elements in Period 3 (Experiment 4.12). However‚ you will not be asked to test the oxides with cyclohexane because unlike the covalent chlorides‚ most of the oxides are not composed of discrete molecules. Therefore they are unlikely to dissolve in cyclohexane and simple experiments cannot distinguish between insolubility and slight solubility.

Nor Amirah Farhana Nawawi Organic Chemistry Lab Report Bo Shen Title: Nucleophillic Substitution Reaction Introduction: This lab experimented on the reactions of the chemicals that undergoes SN1 or SN2 reaction. Nine different compounds were given to be examined with two reagents - NaI in acetone and AgNO3 in ethanol. The SN1 reaction happens in AgNO3 in ethanol reagents‚ and SN2 reaction is in NaI in acetone. Procedure: Following the lab manual. Results: compound NaI /acetone (SN2) AgNO3/ethanol

Subject: Experiment 23: Stereochemistry of the Addition of Bromine to trans-Cinnamic Acid Introduction/Abstract: The purpose of this experiment was to carry out the bromination of trans-cinnamic acid‚ to determine the stereochemistry of the dibromide product of 2‚3-dibromo-3-phenylpropanoic acid‚ and find out whether the reaction proceeds by the usual bromonium ion mechanism or some other mechanism. In this experiment trans-cinnamic acid was mixed with glacial acetic acid and stirred in which

Exercise 5 INTRODUCTION TO STEREOCHEMISTRY I. Introduction Stereochemistry is concerned with the shapes of molecules and how the differences in shapes can effect the properties and reactions of compounds. Subtle differences in molecular shape have far – reaching consequences and it is probably the field of molecular biology that a full awareness of molecular shapes has emerged. A knowledge of the molecular shapes of such vital compounds as sugars‚ amino acids‚ and proteins is essential

Application of linear algebraic equation for chemical engineering problem The chemical engineering system models often outcome of set of linear algebraic equations. These problems may range in complexity from a set of two simultaneous linear algebraic equations to a set involving 1000 or even 10‚000 equations. The solution of a set two or three linear algebraic equations can be obtained easily by the algebraic elimination of variables or by the application of cramer’s rule. However for systems involving
