In the light of the above statements, choose the most appropriate answer from the options given below
Options
- AStatement I is incorrect but Statement II is correct
- BBoth Statement I and Statement II are incorrect
- CBoth Statement I and Statement II are correct
- DStatement I is correct but Statement II is incorrect
Correct answer
A. Statement I is incorrect but Statement II is correct
Step-by-step solution
Statement I: Benzene reacts with nitrating mixture () to form nitrobenzene. However, nitrobenzene is highly deactivated due to the strong electron-withdrawing and effects of the group. Friedel-Crafts reactions (alkylation or acylation) do not occur on strongly deactivated rings like nitrobenzene. Thus, nitrobenzene will not react with to give m-nitroacetophenone. Statement I is incorrect.
Statement II: The group is a meta-directing group because it withdraws electron density from the ortho and para positions more than from the meta position. It is also a deactivating group as it reduces the overall electron density of the benzene ring, making it less reactive towards electrophilic aromatic substitution. Statement II is correct.
Therefore, Statement I is incorrect but Statement II is correct.
Statement II: The group is a meta-directing group because it withdraws electron density from the ortho and para positions more than from the meta position. It is also a deactivating group as it reduces the overall electron density of the benzene ring, making it less reactive towards electrophilic aromatic substitution. Statement II is correct.
Therefore, Statement I is incorrect but Statement II is correct.
