What reagent can effect the following transformation?
Understand the Problem
The question is asking for the specific reagent that can facilitate the transformation of a nitro group (NO2) on a chlorobenzene to an amine group (NH2), while maintaining the chlorine substituent. This involves knowledge of organic chemistry reactions.
Answer
Fe/HCl; then OH.
The reagent required for this transformation is option a) Fe/HCl; then OH.
Answer for screen readers
The reagent required for this transformation is option a) Fe/HCl; then OH.
More Information
This transformation is a reduction of the nitro group to an amino group. Iron in acidic conditions (Fe/HCl) can effectively reduce nitro groups to amines.
Tips
A common mistake is not recognizing that the reduction conditions are specific for nitro to amino conversion.
