The bromination of anisole occurs without the presence of a Lewis acid catalyst and often leads to the formation of tribromide with the presence of excess bromine. Explain why.
A substitution reaction where hydrogen (H) is replaced with chlorine (Cl) is shown below. What ratio of products A, B, and C would you anticipate, given a random statistical distribution and no knowledge of the mechanism of the reaction?
Write a mechanism for the reaction of toluene with bromine in the presence of FeBr3 as a catalyst.
Chlorine gas is added to two flasks containing different compounds: phenyl isobutyl ether and cyclohexene, both dissolved in an organic solvent. Both exhibit loss of chlorine's greenish-yellow tint. What observation would differentiate between the alkene and the aryl ether?
When three equivalents of bromine are added to 3,5-dimethylphenol in CCl4, a product with the molecular formula C8H7Br3O is obtained. This product is further treated with bromine water which results in another product with the molecular formula C8H6Br4O. The IR spectrum of the second product shows a strong absorption at around 1685 cm–1 (similar to that of quinone). Determine the structures of the two products.
Draw the mechanism for the ortho and para bromination of methoxybenzene.
