As you view the graphics, the idea is to develop the concept of polarity in a visual manner. The more areas of red and blue that you see, the more polar is the compound and the functional group in the compound. Look at the amide, and acid. The more areas of gray and lighter shades of red and blue, the more non-polar properties are being depicted. Look at the amine, ether, and alkane.

It has a fine, elegant and delicate appearance, but as a fabric, it has several disadvantages.
1 Because of its natural protein structure, silk is the most hypoallergenic of all fabrics. 2  An all-climate fabric, silk is warm and cozy in winter and comfortably cool when temperatures rise. 3  Its natural temperature-regulating properties give silk this paradoxical ability to cool and warm simultaneously.
