1. Why does performing some Se2 reactions at 0 degrees Celcius allow you to identify the order of reactivity more definitively? 2. Would you expect the relative rate of Se2 reactions to be faster or slower if molecular Chlorine were used instead of molecular Bromine? Explain your reasoning. 3. Which compound would you expect to undergo bromination faster, aniline, C6H5NH2, or acetanilide? Anilinium ion, C6H5NH3+, or aniline? Explain your reasoning.
