Watercolor painting demonstrations, advice, and gallery. Painting the sky and clouds with watercolor. Painting the sky and clouds. After doing the drawing our first watercolor painting step is painting the sky and clouds. Create a very weak mixture of French Ultramarine and Burnt Sienna, about the strength of a weak cup of tea.
In chemistry, polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole or multipole moment. Polar molecules must contain polar bonds due to a difference in electronegativity between the bonded atoms. A polar molecule with two or more polar bonds must have an asymmetric geometry so that the bond dipoles do not cancel each other.
polar, nonpolar, you've spotted those adequately. The thing to remember now is that molecules don't know they're polar or nonpolar, those are just names we come up with to describe our observations. In the case of ethanol, it has a polar bit and a non polar bit- the 'anol' vs the 'eth'. In this molecule, the carbon end is nonpolar enough to drag the polar end into the tolune, and vice versa, the polar end is polar enough as to drag the nonpolar end into water, which is why alcohol mixes with water.
