What is the general formula for alkanes?
Cn H2n+2
What is a saturates hydrocarbon?
Hydrocarbons that contains only single C-C bond
What is homologous series ?
Family of compounds which have similar chemical properties because they have the same functional group
Each member of a homologous series differs from the next by a CH2 group
Is alkanes saturated hydrocarbons?
Yes
Most of the hydrocarbons found in crude oil are from a homogeneous series knows as alkanes
Why is alkanes classified as a saturated hydrocarbon?
Because it contains single C-C bonds
