(b)
Interpretation: The products formed by the treatment of given compound with
Concept introduction: The replacement or substitution of one functional group with another different functional group in any chemical reaction is termed as substitution reaction. The electron deficient chemical species that contains positive charge are known as electrophile. In electrophilic aromatic substitution reaction, electrophile takes the position of hydrogen atom by attacking the electron rich carbon atom of benzene.

Answer to Problem 18.37P
No product will form by the treatment of given compound with
Explanation of Solution
An aromatic compound undergoes Friedel-Craft acylation on reaction with
In the given compound, benzene ring is attached to a strong electron releasing group. However, the Friedel-Craft acylation reaction does not occur in the presence of strong activating groups. Therefore, no product will form by the treatment of given compound with

Answer to Problem 18.37P
The products formed by the treatment of given compound with
Explanation of Solution
An aromatic compound undergoes Friedel-Craft acylation on reaction with
In the given compound, benzene ring is attached to an electron withdrawing group bromine which deactivates the benzene ring and it donates electrons through resonance effect. The ortho position is an electron deficient position than para position due to negative inductive effect, thus the acyl group will go to para position as shown in Figure 4.
