Organic Chemistry · Part 2 of 4
3 exam-style questions with model answers, plus 4 quick multi-choice questions — every question on this part of the standard, grouped by the 1 page of notes they come from.
Write a full answer before you reveal the model one. That comparison is where the learning happens.
State whether each of butan-1-ol, butane and butanoic acid is soluble in water, and identify which has the highest boiling point.
Propanone, CH3COCH3, is very soluble in water but has a boiling point of only 56 °C, much lower than propan-1-ol at 97 °C. Explain both observations.
A mixture contains hexanoic acid and hexan-1-ol, which have boiling points of 205 °C and 157 °C. A student proposes separating them by distillation. Evaluate this proposal, and describe an alternative method based on solubility, justifying why it would work.
