Like dissolves like is actually a good way to look at it but to fully explain...
The four bonds of carbon CCl4 are polar, but the molecule is nonpolar because the bond polarity is canceled by the symmetric tetrahedral shape.
The electrons on H2O are unequally shared, with the oxygen atom is attracted more so to the two lone pairs than the hydrogen atoms. Since the oxygen atom is more attracted to the lone pairs, it carries a partial negative charge.
After explaining this , it still comes back to like dissolves like and by explain this the compound would have to be nonpolar.
A compound that you are studying is soluble in CCl4 but not in water. Would you predict that
the compound is polar or nonpolar? Why? [Please explain; don’t just give a trivial answer such
as “Because like dissolves like”.]
