Esterification Reaction
Esterification occurs between carboxylic acids and alcohols.
The colourfull notes from my students(5H) show reaction between ethanoic acid and different alcohols(methanol, ethanol, propanol and butanol).

| Isomers of butene |
Isomerism occurs in alkene due to
- branching
- position of carbon-carbon double bond
Photos show possible isomers for butene, C4H8. Can you draw their strutural formulae and name them?
Their names are as follows:
Top: but-1-ene
Left: 2-methylprop-1-ene
Right: but-2-ene
