(a)[8]
Fill in Table 4.1 so that you: • name a reagent that can tell the compounds in each pair apart • state the positive outcome of the chemical test and identify which compound shows it. Use a different reagent for each test.
(b)[2]
C1 has melting point $-94^\circ\text{C}$ and boiling point $+49^\circ\text{C}$. Account for these values by referring to the van der Waals’ forces between the molecules.
(c)[1]
Draw the structure of the cis isomer for C2.
(d(i))[1]
When C2 is heated gently, it forms a polymer. Identify the type of polymer produced from C2.
(d(ii))[2]
Draw one repeat unit from the polymer formed by C2.
