Description

In this experiment, the different reactions of primary, secondary and tertiary alkanols with potassium permanganate as oxidant are investigated. To do this, potassium permanganate is added to 1-butanol, 2-butanol and tert-butanol (2-methylpropan-2-ol). While primary and secondary butanol are oxidised, the tertiary 2-methylpropan-2-ol is not. Unlike 1-and 2-butanol, no colour change takes place here. The students realise that the structure of a substance has a great influence on possible reactions. They learn about the substance group of aldehydes and ketones.
