Performance objectives

• Identify and write the molecular formulae of alkanols up to C6.
• Apply IUPAC rules to name alkanols and their isomers.
• Describe the preparation methods of alkanols.
• Explain the characteristic tests for alkanols.
• Discuss the practical uses of alkanols in various sectors.

Lesson summary

Alkanols, commonly known as alcohols, are a vital class of organic compounds we encounter daily. From the locally produced *akpeteshie* and palm wine (which contain ethanol) to the hand sanitizers we use for hygiene, and the rubbing alcohol in our first aid boxes, alkanols are deeply integrated into Ghanaian life. They are also crucial in medicine, industry, and as potential biofuels. In this lesson, we will explore the world of alkanols, learning how to name them, how they are made, what makes them behave the way they do, and how we can identify them.

Lesson notes

2.1 Introduction to Alkanols

Alkanols are a homologous series of organic compounds containing the hydroxyl (-OH) functional group attached to a saturated carbon atom. Their general formula is CₙH₂ₙ₊₁OH, where n ≥ 1.

The "-OH" group is responsible for most of the characteristic properties of alkanols.
