5. As mentioned, structural isomers have different physical and chemical properties. Compare the two molecules to the bottom left. The straight-chain isomer has a higher boiling point than the branched isomer; in the straight- chain isomer there are more sites for London forces to form between adjacent molecules . When isomerism results in different functional groups, differences may exist due to changes in AEN values and polarity a ) Predict which molecule on the right will have a higher boiling point . Explain . b) Which will be more soluble in water ? Explain.
