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.
Classify each alcohol (A, B and C) as primary, secondary or tertiary. In each case, justify your classification by referring to the number of carbon atoms directly bonded to the carbon that bears the \(\mathrm{-OH}\) group.

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.
