Question:
Explain the mechanism of electrophilic substitution in haloarenes with the help of an example.
Explain the mechanism of electrophilic substitution in haloarenes with the help of an example.
Show Hint
In haloarenes, the halogen group directs electrophilic substitution to ortho and para positions.

Verified By Collegedunia
Solution and Explanation
Haloarenes undergo electrophilic substitution due to the resonance effect, which stabilizes the intermediate carbocation. Example:
\[
C_6H_5Cl + Cl_2 \xrightarrow{FeCl_3} C_6H_4Cl_2 + HCl.
\]

What type of isomerism is shown by the complex \([\text{Co(NH}_3)_6][\text{Cr(CN)}_6]\)?
The given coordination compound \([\text{Co(NH}_3)_6][\text{Cr(CN)}_6]\) exhibits ionization isomerism.
**Explanation:** Ionization isomerism arises when two complexes have the same molecular formula but yield different ions in solution. In this case, the cationic complex \([\text{Co(NH}_3)_6]^{3+}\) and the anionic complex \([\text{Cr(CN)}_6]^{3-}\) could interchange their ligands under different conditions, leading to a different complex with distinct properties.
