Butamben is able to act as a base. Complete the equation for a reaction in which butamben acts as a base.
Predict whether butamben is a stronger or weaker base than ammonia. Give a reason for your answer.
Complete the reaction scheme below to show the structural formulae of the products formed when butamben is treated separately with the stated reagent.
State the number of peaks in the spectrum that show a triplet splitting pattern.
On the diagram of butamben below, circle the protons responsible for 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 differ from the proton NMR spectrum 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. $m/e = 92 =$ $m/e = 57 =$
