QUESTION 1 This questiоn is mаinly аbоut аlkenes. A few drоps of bromine water are added to separate test tubes of propane and propene and the mixtures are shaken. (a) Describe what is seen at the end of each experiment for the Propane and the Propene respectively. (2) (b) Give the reagents and conditions for each of these conversions. (i) CH2==CH2 → CH3CH2OH (1) (ii) CH2==CH2 → CH2OHCH2OH (1) (c) Draw the structure of Z-3-methylpent-2-ene. (1) (d) Exactly 720 cm3 of hydrogen gas, measured at room temperature and pressure (r.t.p.), reacted with 0.010 mol of an alkene to form an alkane. Deduce the number of double bonds in one molecule of the alkene. You must show your working. [Molar volume of gas at r.t.p. = 24 000 cm3 mol−1] (2) (e) A student drew a mechanism for the addition of bromine to ethene. See addendum Figure 1.1 Describe the three changes needed to correct this student's mechanism. (3) (f) Part of the structure of a polymer is shown. See addendum Figure 1.2 Draw the structure of the monomer used to make this polymer. (1) TOTAL QUESTION 1: [11]
