Question

would water be more soluble in ethanol or carbon tetrachloride?

would oil be more soluble in ethanol or carbon tetrachloride?

would F2 be more soluble in ethanol or carbon tetrachloride?

Answer 1

Solution.

Solubility Rule - "Like dissolves Like"

• Polar compound is soluble in polar solvent.

• Non polar compound soluble in non polar solvent.

1• water would be more soluble in ethanol than carbon tetrachloride.

REASON-

water is a polar compound and it will dissolve in polar solvent.

Ethanol- It is polar solvent because it has net dipole moment.

Carbon tetrachloride- It is non polar solvent because it has tetrahedral shape so the dipoles cancel out.Giving rise to Zero dipole moment.Hence it is non polar.

So water is more soluble in ethanol than carbon tetrachloride.

2• Oil is more soluble in carbon tetrachloride than water.

REASON-

Oil is a non polar hydrocarbon chain so would soluble in non polar solvent.

Also carbon tetrachloride is non polar. So Oil is more soluble in it.

3• F2 is more soluble in carbon tetrachloride than ethanol.

REASON-

F2 is a non polar due to zero dipole moment.

It would be more soluble in carbon tertrachloride which is non polar.
