| 21. | Though water is a very polar molecule, alkanes and other hydrophobic molecules are more polarizable.
|
| 22. | The oscillation of polar molecules produces frictional heating, ultimately generating tissue necrosis within solid tumors.
|
| 23. | Examples of polar molecules include hydrogen chloride ( HCl ) and chloroform ( CHCl 3 ).
|
| 24. | Polar molecules have a net attraction between them.
|
| 25. | This stationary phase will adsorb polar molecules which can be collected with a more polar solvent.
|
| 26. | This kind of interaction can be expected between any polar molecule and non-polar / symmetrical molecule.
|
| 27. | However polarity also requires geometric asymmetry, or else dipoles may cancel out resulting in a non-polar molecule.
|
| 28. | Typical solvents for ionic polymerization include non-polar molecules such as pentane, or moderately polar molecules such as chloroform.
|
| 29. | The smallest polar molecule is water.
|
| 30. | Typical solvents for ionic polymerization include non-polar molecules such as pentane, or moderately polar molecules such as chloroform.
