1. Composition
These are triesters of glycerol with higher fatty acids.
These are hydrocarbons (saturated). Kerosene oil-Alkanes from C12 to C16.
2. Source
Seeds root and fruits of plants.
These occur inside earth in the form of petroleum.
3. Hydrolysis
Undergo hydrolysis with alkali. Form soap and glycerol.
No hydrolysis occurs.
4. On adding NaOH and phenolphthalein
Decolourisation of pink colour occurs.
No effect.
5. Burning
Burns slowly
Burn very readily.
6. Hydrogenation
Hydrogenation occurs in presence of nickel catalyst. Solid glycerides (fats) are formed.
No hydrogenation occurs.
