Is toluene ortho or para directing?
For example, the nitration of methyl benzene (toluene) will produce ortho and para nitrotoluene as the main product because the methyl group is an ortho‐para director . However, methylating nitrobenzene leads to the formation of meta nitrotoluene because the nitro group is meta directed.
