Title: Experiment 28: Nitration of Methyl Benzoate Objective: The students will learn to nitrate methyl benzoate through electrophilic aromatic substitution reaction. They will learn the importance of regiochemistry in chemical reactions. They might experience disubstitution through a high temperature. Reactions: Observation: The crystals started to form when added 2 g of crushed ice. The addition of hot methanol dissociated the crystals. The crystals reappeared when cooled down in

Trinitrotoluene‚ TNT‚ or 2‚4‚6-trinitrotoluene‚ is a nitro chemical compound with the formula C₆H₂(NO₂)₃CH₃. TNT is a yellow-colored solid and contains in its structure three NO2 groups and one –CH3 group all bonded to carbon atoms on the aromatic ring (Juhasz and Naidu 2007‚ Pichtel 2012). Oxygen and nitrogen are the two highly electronegative elements where oxygen possesses the highest electro-negativity. Subsequently‚ the polarized N–O bonds within the nitro groups makes them easily reducible (Esteve-Nunez

Mona Vaidya April 8‚ 2014 Professor Diaz Chem 317 Section: 20711 Lab Experiment: Nitration of Bromobenzene Introduction: The chemical reaction of nitration consists of a nitro group being added to or substituted in a molecule. Nitration can basically be carried out by a mixture of concentrated nitric acid and sulfuric acid; this 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

likely to only affect the yield result‚ and not the chemical structure of the synthesis. Conclusion Judging by the results from the IR spectra‚ Melting point determination and chemical tests‚ It can be assumed that Benzanilide and Methyl 3-Nitro benzoate were both successfully synthesised. Unknown compound E was identified as compound 6‚ 1-(4-Aminophenyl) ethanoate. Unknown compound B was identified as compound 4‚ 1- (4-Nitrophenyl)

6. Chapter six describes the 9 stages of growth from a neonate to a late adult‚ as well as provides us with the vital signs at various ages. A child when born is a very delicate human being that is still a long way from being fully developed. Then as they grow their body begins to stretch out along with their vitals until about a year of age‚ after that vitals on average should begin to slowly decrease‚ while blood pressure increases. As the infant grows in a child they begin to explore new thing

whilst also manipulating facts in favour of Hollywood glamour. The Gilford Four were sentenced on the basis of false evidence manipulated by the prosecution. Despite the court’s knowledge that nitro-glycerine (a compound used in the manufacturing of explosives) was a common component of dishwashing liquid‚ the nitro-glycerine found on a pair of dishwashing gloves from the residence of the Gilford four was presented to the court in such an indisputable light that left the public with no uncertainty of

Abstract:The Wittig Reaction is a nucleophilic addition in which an alkene is formed as a product. Both the E and Z isomers of the alkene result. Substituents on the aromatic aldehyde affect the E/Z ratio of products that form. In this experiment‚ a nitro group was used as the substituent in the ortho‚ meta and para positions‚ with benzaldehyde as the control. Each of the four aldehydes reacted with (carbethoxymethylene) triphenylphosphorane to produce ethyl cinnamate‚ ethyl-3-(2-nitrophenyl)acrylate
