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 experiment nitration is carried out using acetanilide and allows this chemical to be used in a way that could be beneficial for our use. Procedure Gathering products Weighed out 0.202g of acetanilide powder and add 500µl

TRICARBONYLBENZENECHROMIUM (I) was first obtained by Fischer and Ofele in 27% yield from chromium hexacarbonyl and dibenzenechromium in benzene in a sealed system at 220". We had independently discovered a simpler and more general method for preparing compounds of this type which involves heating chromium hexacarbonyl under reflux in an excess of the aromatic compound or with a molar quantity

unique distinguishing properties. Unlike in alcohols where the hydroxyl group is bound to a saturated carbon atom‚[5] in phenols the hydroxyl group is attached to an unsaturated aromatic (alternating double and single bond) hydrocarbon ring such as benzene.[6] Consequently‚ phenols have greater acidity than alcohols due to stabilization of the conjugate base through resonance in the aromatic ring.

Electrophilic Aromatic Substitution Objective The objective of this experiment was to illustrate electrophilic aromatic substitution by synthesizing p-nitroanilide (as well as ortho) from acetanilide by nitration. The para form was separated from the ortho form based on solubility properties using recrystallization techniques.

SEPERATING CYCLOHEXANE AND TOLUENE BY DISTILLATION Aim: Separate two miscible liquids‚ either by macroscale or microscale process‚ using simple and fractional distillation. Compare the efficiencies of simple and fractional distillation. INTRODUCTION: The purpose of this experiment is to learn how to separate two miscible liquids by microscale process. There will be use of simple and fractional distillation. Simple and fractional distillation efficiencies will be compared. The student should have

UN 1076 – Phosgene HAZARDS: Phosgene is a highly toxic‚ irritating and corrosive gas. Inhalation can cause fatal respiratory damage. Phosgene reacts violently and decomposes to toxic compounds on contact with moisture‚ including chlorine‚ carbon monoxide and carbon tetrachloride. In case of skin contact: If liquid phosgene (below 8.2 deg C) contacts the skin or clothing‚ an inhalation exposure should be suspected. Hazards due to skin contact with the gas is unknown. Phosgene does‚ however‚ react

Nitration of Methyl Benzoate Abstract: This procedure demonstrates the nitration of methyl benzoate to prepare methyl m-nitrobenzoate. Methyl benzoate was treated with concentrated Nitric and Sulfuric acid to yield methyl m-nitrobenzoate. The product was then isolated and recrystallized using methanol. This reaction is an example of an electrophilic aromatic substitution reaction‚ in which the nitro group replaces a proton of the aromatic ring. Following recrystallization‚ melting point and infrared
