Nitration of anisole gives majorly:
Nitroanisole
meta-Nitroanisole
para-Nitroanisole
ortho-Nitroanisole
When anisole is nitrated with a mixture of conc HNO3 and H2SO4 it gives a mixture of ortho-Nitroanisole and para-Nitroanisole (major) products.
Amino group is ortho, para directing for aromatic electrophilic substitution. On nitration of aniline with concentrated acids, a good amount of meta nitro aniline is obtained. This is due to
