The flowchart shows how 2-methylbut-2-ene can be converted into a number of organic products. (a) Complete the flowchart by drawing an organic structure in the box below. 16 H3C H3C CH3 reagent A 2-methylbut-2-ene reaction R mixture of two alcohols KOH(aq) / warm CH3 CH3 H3C OH OH [1] (b) Identify reagent A.[1] (c) In the flowchart, reaction R forms a mixture of two alcohols that are structural isomers of C5H12O. (i) State the reagents and conditions needed for reaction R.[1] (ii) What is meant by the term structural isomers?[1] (iii) Draw the two structural isomers of C5H12O formed in reaction R.OCR 2014 [2]<br />
 (iv) Suggest why 2-methylbut-2-ene is less soluble in water than either of the structural isomers formed. 17[2] (d) Describe the oxidation reactions of propan-1-ol when using a suitable oxidising agent. Indicate how the use of different reaction conditions can control which organic product forms. Include reagents, observations and equations in your answer. In your equations, use structural formulae and use [O] to represent the oxidising agent.[6] [Total: 14]OCR 2014 Turn over<br />
