QUESTION 7 This questiоn is аbоut аlkenes. (а) An alkene has a mоlar mass of 112 g mol−1. Deduce the molecular formula of this alkene. (1) (b) There are a number of different alkenes with the molecular formula C4H8. (i) Draw the structure of the branched-chain alkene with the molecular formula C4H8. (1) (ii) Give the structures and names of the two geometric isomers with the molecular formula C4H8. (2) (c) Two reactions of 1-methylcyclohexene are shown. Refer to addendum Fig 7.1 (i) Draw the skeletal formula of compound X formed in Reaction 1. (1) (ii) Give the reagent and condition needed for Reaction 2. (2) (d) Iodine monochloride, ICl, reacts with alkenes in a similar way to hydrogen bromide. Complete the mechanism for the reaction of iodine monochloride with propene to form the major product. Include curly arrows, the relevant lone pair and the structures of the intermediate and product. (4) Refer to addendum Fig 7.2 (e) A section of a polymer showing two repeat units is given. Refer to addendum Fig 7.3 Give the name of the monomer that forms this polymer. (1) (f) 0.0100 mol of an alkene reacts completely with exactly 600 cm3 of hydrogen gas, measured at 298 K and 1.24 × 105 Pa pressure, to form an alkane. Use the ideal gas equation to deduce the number of double bonds in one molecule of the alkene. You must show your working. [pV = nRT R = 8.31 J mol−1 K−1] (4)
