Title: Solubility of CH3Cl
Post by: Darren on June 20, 2012, 01:28:57 AM
Why is CH3Cl insoluble in water? Shouldnt it dissolve in water because of the common phrase we've heard, 'like dissolves like'? The molecule is polar, so it should dissolve in water?

Chloroform is not polar.

Why isnt it polar? It has a tetrahedral shape and there is one atom different from the rest, which is Cl.

Its some polar , soloubility 8,2 g/l in water.

that means its slightly soluble in water?
Can i generalise that the greater the polarity of the solute, the greater its solubility?

Just a picky point, CH3Cl ≠ chloroform (CHCl3)
