Yeh. CH2Cl2 is barely polar actually since C-Cl has deltaEN=0.5 where C-H gives a 0.4.
Much less polar than water for sure.. Well that explains it. Thanks. I was totally misled by my weird thinking... Egrrr.
I was working on my chem lab, this question occurred to me. Water and dichloromethane are both polar molecule. However, dichloromethane is able to mix with alcohols much better than water. Is there a polarity difference that caused the miscibility to be different?
