  • Bromination Lab Report

    785 Words  | 4 Pages

    hydrogen atom of benzene or benzene derivative is replaced by bromine due to an electrophilic attack on the benzene ring. The purpose of this experiment is to undergo bromination reaction of acetanilide and aniline to form 4-bromoacetanilide and 2,4,6-tribromoaniline respectively. Since -NHCOCH3 of acetanilide and -NH2 of aniline are electron donating groups, they are ortho/para directors due to resonance stabilized structure. Even though the electron donating groups activate the benzene ring, their

    1022 Words  | 5 Pages

    Lab Report 10: Nitration of Bromobenzene Raekwon Filmore CM 244 Section 40 March 27, 2018 Introduction: For this experiment, nitration of bromobenzene was the focus of the lab. The benzene is an aromatic compound and when it reacts with wither a mixture of sulfuric acid or nitric acid creates what is known as a nitro group. The formation of the nitro group is possible because it is an electrophilic aromatic substitution reaction. The creation of the nitronium ion is shown below: The reaction

    was invented by Heinrich Hock in 1944 and also independently by R. Udris and P.Sergeyev in 1942. This process uses to relatively cheap base starting materials benzene and propylene and this creates two much more valuable materials Phenol and Acetone. This is the most popular method to produce Acetone. It is produced by compressing Benzene and Propylene at 30 standard atmospheres at 250 degrees Celsius in the presence of a catalytic lewis acid. This is most likely to be Phosphoric acid as it is usually

    1 Heterocyclic compound 2.1.1 Carbazole Carbazole is an aromatic heterocyclic organic compound. This compound has a tricyclic structure, comprising of two six membered benzene ring fused on either side of a five membered nitrogen-containing ring. The structure of compound is based on the indole structure in which a second benzene ring is fused onto the five-membered ring at the 2–3 position of indole (equivalent to the 4a–9a double bond in carbazole) (Nandy et al., 2014). Using conventional physico-chemical

  • Methanol Extraction Experiment

    1257 Words  | 6 Pages

    In this experiment, extraction was used as a separation technique to separate the acid, base, and neutral compounds. In extraction, two immiscible solvents with opposite polarities are used to dissolve different parts of the solute with different polarities, so they form two distinct liquid layers. In this experiment, methanol, an organic solvent, and an aqueous solution were used as the two immiscible solvents. The extraction solvent must also be capable of dissolving one of the mixture components
