That is‚ the entering group does not for the most part have the same position on the ring as that purged by the halogen substituent. Case in point‚ the hydrolysis of 4-chloromethylbenzene at 340° gives an equimolar mix of 3-and 4-methylbenzenols: Significantly all the more striking is the elite development of 3-methoxybenzenamine in the amination of 2-chloromethoxybenzene.

Determination of the Equilibrium Constant of an Unknown Ester Hydrolysis Reaction Abstract The experiments to follow determined that the equilibrium concentrations of the reaction: ester + water ↔ alcohol + acid‚ are equal to 0.0363 moles of ester‚ 0.2852 moles of water‚ and 0.0268 moles each of alcohol and acid. Using this information the equilibrium constant was determined to be 0.06938. 1. Introduction In this lab the equilibrium constant‚ Kc‚ for the acid catalyzed reaction

Hydrolysis of tert-butyl Chloride in different solvents Practical conducted on 5 March‚ 2013 Reported by Pham Vu Hung on 10 March‚ 2013 Introduction: This practical is meant to measure the rate of reaction of the hydrolysis of tertiary-butyl chloride –a colorless‚ liquid organic compound at room temperature that is sparingly soluble in water - in water/acetone and water/isopropanol mixtures. Since there are many influencing factors for the rate of reaction‚ all are kept constant but the

How has your understanding of Letter Two reshaped your understanding of marriage and female identity in Pride and Prejudice? In Weldon’s novel‚ Letters to Alice‚ she scrutinises and exposes the reality that women faced in the Regency period in regards to marriage and female identity. This forces the reader to rethink their prior views of women that were shaped by Austen’s context‚ thus appreciating her novel on a deeper level. In comparison to Austen’s text which emphasises the necessity for Georgian

Purpose The purpose of this experiment is to determine the rate constants‚ k1‚ for the methyl acetate hydrolysis reaction at 25 °C and 35 °C‚ as well as the overall activation energy of the reaction. Methods Methyl acetate was placed in an HCl solution‚ in which it reacts with water to form acetic acid over time. At each time interval‚ an aliquot of the mixture was removed for titration against NaOH to determine the concentration of the acetic acid produced. From the amount of acetic acid produced

Jane Austen’s 1813 novel‚ ‘Pride and Prejudice’ and Fay Weldon’s 1984 epistolary text‚ ‘Letters to Alice on First Reading Jane Austen’ (Letters to Alice) are written regarding their individual contexts. A parallel study of these two didactic texts‚ composed in different centuries‚ develops a deeper understanding of the opposing values in relation to their own society. When read as a pair the obvious connection of societies failure to accommodate women’s happiness as a worthwhile moral project highlights

Pride and Prejudice is‚ first and foremost‚ a novel about surmounting obstacles and achieving romantic happiness. For Elizabeth‚ the heroine‚ and Darcy‚ her eventual husband‚ the chief obstacle resides in the book’s original title: First Impressions. Darcy‚ the proud‚ prickly noblewoman’s nephew‚ must break free from his original dismissal of Elizabeth as “not handsome enough to tempt me‚” and from his class-based prejudice against her lack of wealth and family connections. Elizabeth’s first impressions

Abstract: The main reason for this experiment is to prepare a simple soap made from vegetable oil. The physical properties will be tested in order to demonstrate the reactions that occur. The experiment can conclude that the vegetable oil had a primary fatty acid called linoleic acid‚ which was evident during the saponification reaction. The simple soap did appear to be a good emulsifier because the soap did dissolve in the mixture of mineral oil and water. In hard water the calcium and magnesium
