(Solved): experiment #18? Electrophilic Aromatic Substitution: Bromination of Acetanilide. 3. What specie (exa ...

3. What specie (exact name) is the electrophile for this reaction? 4. Comment about the comparison of the infrared spectra of acetanilide, p-bromoacetanilide and your product, in regard to peaks (or absence of peaks) in your product that support the formation of $\mathrm{p}$ bromoacetanilide. 5. Comment about the comparison of the melting points for acetanilide, $p$-bromoacetanilide and your product, in regard to your melting point supporting the formation of $\mathrm{p}$-bromoacetanilide. 6. What does a melting point that is not at a temperature for a specific compound imply, assuming that you have pure bromoacetanilide? Acetanilide $+{\mathrm{Br}}_2$
