alkyl halides‚ which are able to undergo chemical transformations more readily than the carbon-carbon double bond‚ onto the trans-stilbene the addition process of halogenation in needed. The typical reagents that are used‚ such as elemental bromine and liquid bromine‚ are dangerous and highly corrosive‚ so this experiment used an alternative method of bromination.

1691 Strong 4. The reaction of the unknown with bromine gave a negative result meaning the solution did not turn clear‚ but rather‚ maintained an orangish brown color. This is interpreted to mean that bromine in not adding to either side of an alkene bond‚ so there is no C=C bond in the unknown compound. The reaction of the dicarboxylic acid with bromine gave a positive result meaning that the solution turned clear as a result of bromine adding to both sided of the C=C bond. The dicarboxylic

tribromide instead of 4-bromoaniline. preparing the 4-bromoaniline involves the attack of a strong electrophile and the hydrolysis of a proton to give the final product. Chemicals and Safety: Bromine is very poisonous‚ and can cause burns. Eyes‚ skin and nose should be protected while carrying the bromine inside the hood. Glacial acid is also a very corrosive compound and can cause severe burns when it’s reacting with aromatic compounds. Also‚ the organic waste was disposed in the halogenated waste

EXP-10 CHEM 233L SYNTHESIS OF p-BROMOANILINE Introduction: In this experiment‚ p-bromoaniline was synthesized in three steps starting from aniline. Since the amino group of aniline is a strong activator of aromatic ring‚ direct bromination is impractical (equation 1). In order to make a desired product‚ amino group needed to be protected as the acetamide which also maintained ortho and para position but slowed down the rate of reaction (equation 2). Slow reaction rate would increase

Bromobenzene undergoes no reaction for both SN1 and SN2. This is because bromobenzene is very stable‚ and contains allylic and vinyllic bromine‚ which is also very stable‚ and cannot be a good nucleophile. Bromocyclopentane reacts under SN1 and SN2‚ but it shows a faster reaction in AgNO3/ethanol reagent‚ that is SN1. This is because bromocyclopentane is secondary bromine‚ and have bigger steric strain‚ since it is a cyclic compound. The bigger steric in a molecule‚ the harder it is for the nucleophile

todifferentiate their intrinsic physical properties and chemical properties in terms ofstructure and behaviour. Nitration test (test for the presence of aromatic ring)‚ Bromine test (test for the presence of unsaturation)‚ and Basic oxidation test (test for an alkyl substituted benzine) were done. We were given an unknown which we tested (Nitration‚Bromine‚ Basic oxidation) and found out that it was an aromatic unsaturated hydro carbon.
