When do methyl groups direct benzene to the 3 position?
Methyl groups direct new groups into the 2- and 4- positions, but a nitro group, -NO 2, already on the ring directs incoming groups into the 3- position. For example, if the temperature is raised above 50°C, the nitation of benzene doesn't just produce nitrobenzene - it also produces some 1,3-dinitrobenzene.
When does methylbenzene react with fuming sulphuric acid?
The effect of this greater reactivity is that methylbenzene will react with fuming sulphuric acid at 0°C, and with concentrated sulphuric acid if they are heated under reflux for about 5 minutes.
Is it possible to substitute chlorine for methylbenzene?
This is a good example of a case where what is already attached to the ring can also get involved in the reaction. It is possible to get two quite different substitution reactions between methylbenzene and chlorine depending on the conditions used. The chlorine can substitute into the ring or into the methyl group.
What happens when you substitute Nitro for methylbenzene?
The nitration of methylbenzene If you substitute a nitro group, -NO2, into the benzene ring in methylbenzene, you could possibly get any of the following products: The carbon with the methyl group attached is thought of as the number 1 carbon, and the ring is then numbered around from 1 to 6.
