Question 1
Paper 2Medium8 marksA student compares five oxygen-containing organic compounds used as solvents. Their structural formulae are shown in Figure 1.
(a)[1]
Determine the molecular formula shared by compounds A–E.
(b)[2]
Identify one pair of position isomers among compounds A–D and explain the structural feature that makes them position isomers.
(c)[2]
Identify a pair of primary alcohols in Figure 1 that are straight-chain/branched-chain isomers, and explain the difference in their carbon skeletons.
(d)[2]
Classify the relationship between compounds A and E as a type of structural isomerism. Give a structural feature that supports your answer.
(e)[1]
State whether compound D is a primary, secondary or tertiary alcohol.
