Alkanes
How is the mass effected?
Mass increases going down because the chain gets longer

5 -- 16
Which alkanes are solids at room temperature?
>16
What are alkanes?

What is the reaction of alkanes?
They are not very reactive
Why do melting and boiling points increase going down?
They destroy the bonds between molecules so the strength of the bonds between molecules increase going down
How are melting and boiling points effected?
They increase going down
What keeps the molecules together?
Van Der Waal's forces
Alkane + oxygen ------>
carbon dioxide + water
Propane + oxygen ------>
carbon dioxide + water
Methane + chlorine ----->
chloromethane + hydrogen chloride
