What are assigning oxidation numbers?

Show answer

Apply these rules in order until every atom is assigned:

What is redox in everyday chemistry?

Show answer

Redox reactions are everywhere: combustion of fuels, respiration in cells, photosynthesis, the rusting of iron, bleaching, and the operation of every battery. Recognising redox quickly through oxidation-number changes lets you analyse all of these with one framework. In Unit 4 the same electron-transfer ideas reappear in the oxidation of alcohols to aldehydes, ketones and carboxylic acids, so the skill of assigning oxidation numbers and identifying the oxidant and reductant carries directly into organic chemistry.
