Alkanes
Muhtasari
The alkanes are the simplest and most familiar organic family: the methane in natural gas, the propane in camping stoves, the petrol in cars. They are the workhorse fuels of the modern world, prized for the energy they release when they burn.
In this lesson you will learn that alkanes are saturated hydrocarbons with the general formula CnH2n+2, why they are generally unreactive, and the two reactions you must know: combustion in air and substitution with halogens in ultraviolet light.
Malengo
- [Core] State that the bonding in alkanes is single covalent and that alkanes are saturated hydrocarbons
- [Core] Describe the properties of alkanes as being generally unreactive, except in terms of combustion
