(a) An alkene was prepared by the dehydration of pentan-1-ol using concentrated sulphuric acid. Name the alkene produced and give its structural formula. (2 marks) (b) Name and give the structural formula(e) of the product(s) of reaction of the alkene from part (a) with: (i) hydrogen (ii) hydrogen bromide (iii) chlorine Marks) (c) Three unknown pure liquid organic compounds \( \mathbf{A}, \mathbf{B} \) and \( \mathbf{C} \), each possessing only one type of functional group, were chemically tested and the following observations reported in a laboratory notebook. Organic Compound Test / Brady's Reagent Test / Tollen's Reagent Test / Oxidation Based on these recorded tests and observations, deduce the functional group present in compound \( \mathbf{A}, \mathbf{B} \) and \( \mathbf{C} \), explain your reasoning.
