Identify the correct statement/s from the following options: (A) -mathrmOCH_3$-\mathrm{OCH}_{3}$ and -mathrmNHCOCH_3$-\mathrm{NHCOCH}_{3}$ are activating groups (B) -mathrmCN$-\mathrm{CN}$ and -mathrmOH$-\mathrm{OH}$ are meta directing groups (C) -mathrmCN$-\mathrm{CN}$ and -mathrmSO_3mathrmH$-\mathrm{SO}_{3}\mathrm{H}$ are meta directing groups (D) Activating groups act as ortho- and para- directing groups (E) Halides are activating groups Choose the correct answer from the options given below :

### Core Logic Let's evaluate each statement based on electrophilic aromatic substitution guidelines: * Statement (A): Both -mathrmOCH_3$-\mathrm{OCH}_{3}$ and -mathrmNHCOCH_3$-\mathrm{NHCOCH}_{3}$ have lone pairs on the atom directly attached to the benzene ring. These lone pairs undergo resonance delocalization into the ring, increasing electron density and activating it toward substitution. This statement is true. * Statement (B): While -mathrmCN$-\mathrm{CN}$ is a deactivating meta-directing group, -mathrmOH$-\mathrm{OH}$ is a strongly activating ortho/para-directing group due to resonance. This statement is false. * Statement (C): Both -mathrmCN$-\mathrm{CN}$ and -mathrmSO_3mathrmH$-\mathrm{SO}_{3}\mathrm{H}$ withdraw electron density via inductive and resonance effects (-I, -M$-I, -M$). This deactivates the ring and directs substitution to the meta position. This statement is true. * Statement (D): Activating groups increase electron density primarily at the ortho and para positions via resonance, directing incoming electrophiles to those sites. This statement is true. * Statement (E): Halogens are an exception: they are deactivating due to their strong inductive effect (-I$-I$), but ortho/para-directing due to resonance (+M$+M$). This statement is false. Therefore, statements (A), (C), and (D) are correct, which matches Option (1). ### Pattern Recognition Groups that activate the aromatic ring by donating electrons via resonance always direct incoming electrophiles to the ortho and para positions. Halogens are a unique exception: they deactivate the ring but still direct to the ortho and para positions. ### Evaluation Rubric / Model Answer null ### Chapter Mix Class 11 Chemistry: Hydrocarbons Class 12 Chemistry: Haloalkanes and Haloarenes
