With some chemical knowledge, you can fairly easily guess if a molecule will be polar or not. Each atom will have a different level of electronegativity, or ability to attract electrons. Actually calculating the polarity of a molecule precisely, however, requires determining the shape of the mole...

Determine if the bonds in the molecule are covalent or ionic. Ionic bonds occur between ions, atoms which have become either negatively or positively charged when their number of electrons are no longer equal to their number of protons. Atoms in such bonds can be considered polar, but only at...

Water molecules cling to cellulose and climb along it through a process called capillary action — cellulose can even defy gravity in order to pull the water along its surface. Because water is a polar molecule, meaning one side of it holds a more positive charge and the other end a more ...
What substance is more necessary to our existence than any other? Water. At its most basic, water is a molecule with one oxygen atom and two hydrogen atoms, bonded together by shared electrons. It is a V-shaped polar molecule, which means that it's charged positively near the hydrogen ...
a scientific and systematic way. In order to overcome such limitations, many techniques have been employed such as solubilization in a non-polar solvent, preparing them as an injection and/or converting the active ingredients into their salt form in order to enhance their solubility in aqueous ...
However, the validation of the pharmacological effect of a drug molecule is a result of drug's inhibition of its intended molecular target may also be challenging since the pharmacological effect (efficacy and toxicity) of the molecule may be due to the inhibition of some unknow molecular targets...
between the two elements. If the electronegativities of both elements are very similar or the same, the bonds are non-polar. If this is the case, the entire molecule is also non-polar. If it has polar bonds, you must examine the molecule further to determine whether it is polar or ...
