2. Propene is an important starting material for many products. The following shows some compounds which can be made from propene, C3H6. Propene (C3H6) C3H7CI C3H80 C3H60 d(i). State the reagents for the conversion of the compound C3H80 formed in (a)(iv) into C3H60. [1] d(ii). Explain why the compound C3H80, produced in (a)(iv), has a higher boiling point than compound C3H60, produced in d(i). [2] d(iii). Explain why the 1H NMR spectrum of C3H60, produced in (d)(i), shows only one signal. [1] e. Propene is often polymerized. Draw a section of the resulting polymer, showing two repeating units. [1]
