WebJul 19, 2024 · You can see why the methoxy group directs to the ortho and para positions by looking at the intermediate carbocation for both the para substitution and the meta addition, shown in the next figure. ... For example, take the bromination reaction of nitrobenzene, shown in the next figure. Nitro groups are electron-withdrawing groups, so … WebFeb 1, 2024 · In FTIR analysis, due to the different peak positions of each bond of the various functional groups, redshift occurs (Table 2). Due to the existence of bond energy and repulsive force, the determination of an N-functional group is easily affected by other atoms or other functional groups, thus resulting in some deviation.
