9. the substance X is not Y is a molecule polar molecular compounds have chemical bond is the Z pole sections do not have polarity if the size of the molecules of a substance X > Y > Z, X Y and Z, what message should be:
9. substance X is a non-polar molecules of the substance Z Y is a polar molecule is non-polar bonds. If the size of the molecules of X> Y> Z XY and Z, then the substance should be the last one.
9) X is a non-polar molecule substance Y is a polar molecule. The substance Z is non-polar bond if the size of the molecules of the X > Y > Z and X substances. Y Z and should be as any.
