dipole moment

(1/1)

dexangeles:
Can someone explain why chloromethane is categorized under "non-polar" eventhough it has a permanent dipole moment (1.9-2.0) that is even greater the water (1.8)

Demotivator:
Chloromethane is a polar molecule.
However, there are those who use fast and loose characterizations to distinguish compounds that are miscible in water from those that are not.

dexangeles:
yes it's polar but they still catgeorize it under non-polar when it comes to bonding

it uses a induced-dipole induced-dipole force to bond to each other, why when it already is polar?

Demotivator:
Who is they?
These articles don't characterize it like that (no induced-dipole).

dexangeles:
if you look up bonding of CH3Cl induced dipole - induced dipole is what's used to describe the bonding

even my Gen Chem and Organic books say it, but don't reason out why  :(
