1 This question is about organic compounds that contain a halogen atom or a
nitrogen atom.
(a) Equal amounts of four bromoalkanes were added to separate test tubes
containing 2 cm3 of a silver nitrate solution.
The mixtures were heated in a water bath.

(1)
A 1‑bromobutane
B 2‑bromobutane
C 1‑bromo‑2‑methylpropane
D 2‑bromo‑2‑methylpropane
(b) Which pair of reactants will form an N‑substituted amide?
(1)
A CH3COCl and NH3
B CH3CH2OH and NH3
