What is Polarity? - A polar molecule is one that contains positive and negative poles. In a polar molecule, a dipole moment exists. In a nonpolar molecule, no dipole moment exists. More on Polarity and its types @ BYJU’S.

chemical process proposed by Massart in 1979[1°1, leads to the synthesis, in aqueous media, of versatile prod-ucts: the nanoscale magnetic particles have a very re-active surface allowing the stabilization of the particles in a large spectrum of media including both polar and non polar ...
Microwave chemistry is the study of chemical processes using microwave radiation. Microwaves heat any medium containing mobile electric charges, such as polar molecules in a fluid or conducting ions in a solid, by acting as high frequency electric fields. Polar solvents heat up because their ...
of the atoms in some molecules is such that one end of the molecule has a positive electrical charge and the other side has a negative charge. If this is the case, the molecule is called a polar molecule, meaning that it has electrical poles. Otherwise, it is called a non-polar ...

For volatile organic compounds (VOCs) to be released from the plant cell into the atmosphere, they have to cross the plasma membrane, the cell wall, and the cuticle. However, how these hydrophobic compounds cross the hydrophilic cell wall is largely unkn
