Boiling Points
« on: September 26, 2011, 07:13:24 PM »
Hey, i was wondering if someone could answer my question on boiling points.
I get the general idea of Organic Chemistry, i find it fairly easy, but i always get confused when they ask why would this compound boil before this other one. ):
For example:
The relative boiling points of three halogen substituted ethane compounds are:
chloroethane: 12.3 C
bromoethane: 38.2 C
idoethane: 72.3 C
Can someone please explain it to me? (:

The boiling points of those increase because of the higher molecular weight of the halogen and stronger intermolecular forces. Look up physical properties of haloalkanes.
