Question

5. (3 points) Predict all the major products of the Balance the reactions. all the major products of the following electrophilic aromatic substitution reactions. HO, H,SO + HNO, SOH FeCl3 + Cl2 NO

Answer 1

in below reaction ortho position of phenol is more electron-rich therefore reaction will occur at that position

=z- HOOC OH N - HOOC

in below reaction ortho position of phenol is more electron-rich therefore electrophilic substitution will occur at that position

NO2 NO2 ΗΝΟ; H2SO4 NO2 OH

in the below reaction meta-position is more electron-rich due to the electron-withdrawing nature of NO2 and SO3H group. therefore electrophilic substitution will occur at that position

SO3H SO3H FeCl3 Cl2 NO2 NO2
