8.When water boils, what effect does the thermal energy produced by the boiling have on the hydrogen bonds? The high temperature causes them to rip apart. 9.Will a non-polar molecule, like pentane, form any hydrogen bonds with water molecules? No, it will not be able to form any hydrogen bonds with water molecules. 10. If pentane is added to water, what happens? All the water molecules will line up in a certain way around the aliphatic molecule. 11. Is entropy increased or decreased when pentane is added to water? Decrease 12. Is a molecule with a carboxyl group on it hydrophobic or hydrophilic? Hydrophilic 13. Do hydrophobic and hydrophilic tendencies affect the overall behaviour of molecules? Yes, hydrophobic and hydrophilic tendencies have great affects on the overall behaviour of molecules 14. Is it possible for one molecule to have a hydrophobic end or area and a hydrophilic end or area? Yes 15. What happens if thousands or millions of molecules, each having two long hydrophobic tails on one hydrophilic head, are put into water? Structure will form called a micelle, where a little globular sphere with the lipid tails tucked inside. 16.What is the name of the structure formed by soap molecules in water? Micelle
