A flavour-and-fragrance company is comparing three candidate alcohols (A, B and C) to use as a solvent in a new room-spray formulation. The alcohols are structural isomers with molecular formula \(\mathrm{C_4H_{10}O}\). Their condensed structural formulae are:
The company is interested in how the structure (including the type of alcohol functional group) relates to physical properties such as boiling point and water solubility.
The measured boiling points are: A = 117\(^\circ\)C, B = 100\(^\circ\)C, C = 82\(^\circ\)C. Use structural arguments to explain this trend in boiling point. Your answer should refer to intermolecular forces and how branching affects them.

Students focus on the principles and applications of chemical synthesis in the field of organic chemistry. Current and future applications of chemistry include techniques to synthesise new substances – including pharmaceuticals, fuels and polymers – to meet the needs of society. Each class of organic compounds displays characteristic chemical properties and undergoes specific reactions based on the functional groups present. These reactions, including acid/base and oxidation reactions, are used to identify the class of an organic compound. In this module, students investigate the many classes of organic compounds and their characteristic chemical reactions. By considering the primary, secondary and tertiary structures of organic materials, students are provided with opportunities to gain an understanding of the properties of materials – including strength, density and biodegradability – and relate these to proteins, carbohydrates and synthetic polymers.
Inquiry question: How can alcohols be produced and what are their properties?
explain the properties within and between the homologous series of alcohols with reference to the intermolecular and intramolecular bonding present
