Topic: Bromination of Toluene
Answers to Common Questions
What is the product of toluene + bromine?
Brominated toluene is the product. Assuming that one Br atom reacts with one toluene molecule there are two possible products depending on the reaction conditions. One is nuclear bromination in the benzene nucleus C6H5 to form CH3.C6H4.Br a... Read More »

What is the chemical equation for toluene + bromine?
Toluene is methylbenzene.CH3-benzene. If you react it with Br2 you will get a substitution reaction of the methyl side chain, so you'll make CH2Br-benzene. You would need much more rigorous reaction conditions make Br attach to the benzene ... Read More »

When you react toluene with Br2 in the presence of FeBr3 catalyst, you will get a mixture of 2-bromotoluene and 4-bromotoluene. The CH3 group is a ortho- and para- directing activator for electrophilic substitution on the benzene ring. Read More »

Bromine in water will readily react with alkenes and alkynes, but not alkanes and aromatics like toluene. The Br2 adds across the double bond in the case of alkenes, and two moles of Br2 will add across the triple bond in alkynes. Bromine w... Read More »

Ethoxybenzene > toluene > iodobenzene > benzaldehyde. Ethoxy is an electron-donating group, which will increase the electron density in the ring and make the reaction occur more quickly, since the benzene ring itself is the nucleophile. Sam... Read More »

Here they use FBr, EtOH and FCCl3 Rozen, S.; Brand, M.; Lidor, R.; J Org Chem [JOCEAH] 1988, 53 (23), 5545. You need a lewis acid to do it in not to hard conditions. Photochemical approach will be nice too, like Br2, FeBr3, hv room temp. Read More »

Aqueous bromine is bromine dissolved in a water based solution. Usually HBr and H20. Your bromine preparation did not mix with either hexane or toluene because of their non-polar nature. They are non-miscible with water. Gaseous bromine, ei... Read More »
