This question is about bromoalkanes with the molecular formula $$\(\mathrm{C}_{4} \mathrm{H}_{9} \mathrm{Br}\)$$. Give the structure of the $$\(\mathrm{C}_{4} \mathrm{H}_{9} \mathrm{Br}\)$$ bromoalkane that would react fastest with aqueous silver nitrate in ethanol. (4) (ii) Complete the mechanism for reaction R3. Include curly arrows, and any relevant lone pairs, dipoles and charges. (4) (iii) Give the wavenumber range of an absorption in the infrared spectrum of the organic product of reaction R 4 , which is not present in the infrared spectrum of $$\(\mathrm{CH}_{3} \mathrm{CH}_{2} \mathrm{CH}_{2} \mathrm{CH}_{2} \mathrm{Br}\)$$. Indicate the bond responsible for this absorption.
