Alkanes
Muhtasari
Alkanes are the simplest family of hydrocarbons and the main components of crude oil fractions. Their single carbon-carbon bonds make them relatively unreactive, but under the right conditions they undergo substitution reactions with halogens.
In this lesson you will learn the general formula for alkanes, why they are called saturated hydrocarbons, how to draw structural and displayed formulae for the first five members, and what happens when alkanes meet halogens in ultraviolet light.
Malengo
- Know the general formula for alkanes
- Explain why alkanes are classified as saturated hydrocarbons
- Understand how to draw the structural and displayed formulae for alkanes with up to five carbon atoms
- Describe the reactions of alkanes with halogens in the presence of ultraviolet radiation
