Which series of reagents would be required to perform the following synthesis?

A) 1. ClCH₂CH₂CH₃, AlCl₃ 2. FeBr₃, Br₂
B) 1. ClCOCH₂CH₃, AlCl₃ 2. FeBr₃, Br₂
C) 1. ClCOCH₂CH₃, AlCl₃ 2. FeBr₃, Br₂ 3. Zn(Hg) , HCl
D) 1. ClCOCH₂CH₃, AlCl₃ 2. Zn(Hg) , HCl 3. FeBr₃, Br₂

The synthesis involves the use of ClCOCH2CH3 as a starting material, which requires acetyl chloride (ClCOCH3) and aluminum chloride (AlCl3) in the first step to form the intermediate. The second step involves the use of FeBr3 and bromoethane (C2H5Br) to introduce the ethyl group onto the aromatic ring. The final step involves the reduction of the nitro group to an amine using Zn(Hg) and HCl. Therefore, the correct series of reagents would be ClCOCH3, AlCl3; FeBr3, C2H5Br; Zn(Hg), HCl. Option C contains these reagents in the correct order. Option A and B are incorrect because they contain different reagents that do not serve the same purpose as the required reagents. Option D is incorrect because the order of reagents is not correct.
