Lessons in this topic
- 0 Start here A roadmap: shared pairs, four slots, chains, groups, families, two compounds and soap. · 4 min You are here
- 1 The bond that shares Some atoms fill their outer shell by sharing electrons. The shared pair counts for both atoms. · 8 min
- 2 Why carbon builds everything Carbon has four bond slots and bonds to itself, so it makes chains, branches and rings. · 8 min
- 3 Single or double A chain of single bonds is saturated. A double or triple bond makes it unsaturated, and a test finds it. · 8 min
- 4 One part swapped Swap one hydrogen on a chain for a group and the family changes. The group decides the family. · 8 min
- 5 A family with one difference Compounds with one group, each one CH₂ apart, form a homologous series. · 8 min
- 6 Ethanol The two-carbon chain with –OH. It dissolves things, burns, and stays liquid in the cold. · 8 min
- 7 Ethanoic acid A CH₃ joined to –COOH. It is a weak acid, and vinegar is its dilute solution. · 8 min
- 8 Soaps bridge oil and water A soap molecule has an oil-liking tail and a water-liking head. That bridge cleans. · 7 min
- 9 Naming a compound The stem counts the carbons. The ending names the group. · 8 min
- 10 An acid and an alcohol make an ester An acid and an alcohol make an ester and water. · 8 min
- 11 An ester and an alkali An alkali breaks an ester into an alcohol and a salt. · 8 min
- 12 Checkpoint: bonds, names and esters Six marked questions on carbon, its groups and its reactions. · 6 min
- 13 The big picture Eleven ideas in one table, from the bond to soap. · 4 min
- 14 Track quiz Eleven quick questions, one for each lesson. Use the table if you get stuck. · 8 min
