Draw the mechanism and label products and reactants for the synthesis of aniline to 4-Bromo-2-Chloroacetanilide:
Aniline + Acetic Anhydride --> Acetanilide + Acetic Acid
Acetanilide + Bromine --> 4-Bromoacetanilide
STEP 1: Hydrochloric Acid + Sodium Chlorate --> Chlorine + Water + Sodium Chloride
STEP 2: 4-Bromoacetanilide + Chlorine --> 4-Bromo-2-Chloroacetanilide
4-Bromo-2-Chloroacetanilide + Ethanol --> 4-Bromo-2-Chloroaniline + Ethyl Acetate
Show all lone pairs or formal charges.

The mechanism involves donation of a hydride from ethanol to reduce the diazonium salt as shown here. After the first reaction (Step 1), each subsequent reaction uses the product of the previous step. The amounts of all reagents used, including solvents, must be sealed according to the amount of product obtained in the previous step (after saving at least 25 mg of the product for characterization and spectral analysis in each step).
