3 This question is about alkanes and their reactions. (a) What is the IUPAC name for this alkane? | A 4-ethyloctane | B 5-ethyloctane в с 3propylheptane D 5-propylheptane (b)

What is the name of the process that could be used to produce propane, C;Hs,from decane, C10H„? E A substitution | B reforming | C fractional distillation | D cracking (c) A student researched the reaction of propane with bromine and found that thereaction could be used to make 1-bromopropane. \mathrm{C}_{3} \mathrm{H}_{8}(\mathrm{~g})+\mathrm{Br}_{2}(\mathrm{l}) \rightarrow \mathrm{C}_{3} \mathrm{H}_{7} \mathrm{Br}(\mathrm{l})+\mathrm{HBr}(\mathrm{g}) The first step of the reaction involves A heterolytic bond fission to form free radicals B heterolytic bond fission to form ions C homolytic bond fission to form free radicals D homolytic bond fission to form ions (ii) A source from the internet gave the percentage yield for this reaction as 31.0%.The best explanation for the low percentage yield of 1-bromopropane in thisreaction is 8 A bromine is very unreactive X Ba gaseous reactant always gives a low yield | C the reaction is very slow | D the reaction produces a mixture of organic products (iii) Calculate the volume of propane, in dm', measured at room temperature and pressure, that is needed to produce 14.7 g of 1-bromopropane, assuming a percentage yield of 31.0%. Give your answer to an appropriate number of significant figures.
