Neco Model Questions Vol1 2018 Chemistry Question 18
Practice objective / multiple choice question 18 from the 2018 Neco Model Questions Vol1 Chemistry examination.
A condensation polymer is formed from monomer A \((\mathrm{C}_{4}\mathrm{H}_{6}\mathrm{O}_{2})\) and monomer B \((\mathrm{C}_{2}\mathrm{H}_{4}\mathrm{O})\). Each repeat unit results from the combination of one A and one B with the loss of one molecule of water. A polymer chain contains 30 repeat units and is terminated by an -OH group from monomer A at one end and an -H group from monomer B at the other end. (a) Write the molecular formula of the polymer. (b) State its degree of polymerisation. (c) Calculate the percentage by mass of carbon in the polymer (atomic masses: C = 12.01 g mol\(^{-1}\), H = 1.008 g mol\(^{-1}\), O = 16.00 g mol\(^{-1}\)).
