Butamben is able to behave as a base. Complete the equation for the reaction in which butamben behaves as a base.
Predict whether butamben is a stronger base or a weaker base than ammonia. Give a reason for your response.
Complete the reaction scheme below so that it shows the structural formulae of the products obtained when butamben is treated separately with the reagent stated.
State how many peaks in the proton NMR spectrum of butamben in $\text{CDCl}_3$ exhibit a triplet splitting pattern.
On the butamben diagram below, circle the protons that produce the peak or peaks you identified in (c)(i).
Describe and explain how the proton NMR spectrum of butamben in $\text{D}_2\text{O}$ would be different from that of butamben in $\text{CDCl}_3$.
The mass spectrum of butamben has peaks at $m/e = 92$ and $57$. Identify the fragments responsible for these peaks.\n\n$m/e = 92 = \\ldots$\n\n$m/e = 57 = \\ldots$
