Lab 8- nitration of Methyl I Benzonate Date of experiment: INTRODUCTION: The nitration of methyl benzoate is an example of an electrophilic aromatic substation reaction. In the experiment the electrophile was the nitronium ion and the aromatic compound was methyl benzoate and with addition of nitrating solution Methyl 3-nitrobenzoate was the product.

Classification Tests for Hydrocarbons Authors: Goldie Ann Tejada‚ Allain Joseph S. Templo‚ Kristinlyn Trajano‚ Kevin Viray‚ Quennie Yu Group 10‚ 2F-PH‚ Faculty of Pharmacy‚ University of Santo Tomas ABSTRACT The test compounds undergo different physical and chemical tests to differentiate their intrinsic physical properties and chemical properties. Physical state‚ color‚ and odor were noted through simple observation. Miscibility of the test compounds were noted through color change or a warming

[2] Nitration is a type of chemical reaction which a nitro group is added to or substituted in a molecule. It can be carried out by a mixture of concentrated nitric acid and sulfuric acid. Mixture is useful to obtain the active 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. [3] In this

The purpose of the experiment was to perform an electrophilic addition reaction by the bromination of cinnamic acid. The product of this reaction is 3-Phenyl-2‚3-dibromo propionic acid‚ which is purified by recrystallization. Cinnamic acid (3-phenylprop-2-enoic acid) is an unsaturated carboxylic acid. The electron rich π cloud (see Figure 1) in the double bond of this structure is nucleophilic and can be considered a Lewis base. It can therefore be saturated by the addition of a halogen to the double

The first objective aims to synthesize an isomer of alkenes. This was done by converting maleic acid to fumaric acid. This conversion was accomplished by applying a heat-catalyzed reaction on maleic acid

163 CHAPTER 13 HYDROCARBON Hydrocarbons are composed of Carbon and hydrogen. The important fuels like Petrol‚ kerosene‚ coal gas‚ CNG‚ LPG etc. are all hydrocarbons or their mixture. Sources: Petroleum and natural gas are the major sources of aliphatic hydrocarbon while coal is an important source of aromatic hydrocarbons. The oil trapped inside the rocks is known as petroleum. PETRA – ROCK‚ OLEUM – OIL. The oil in the petroleum field is covered with a gaseous mixture known as natural
