Every chemical group of a given molecule is characterized by a pattern of electrostatic polarization that dictates the group's reactivity towards other molecules. The polarization of carbonyl (C=O ...

Due to their natural polarity—where the carbon carries a partial positive charge and the oxygen carries a partial negative charge—synthesizing compounds with two carbonyl groups at a very ...

Researchers at Leipzig University have developed a new process for reversing the polarity of chemical compounds, also known as umpolung, for the precise synthesis of pharmaceuticals. This ...

Switching DNA and RNA on and off Date: August 21, 2018 Source: Springer Summary: DNA and RNA are naturally polarized molecules. Scientists believe that these molecules have an in-built polarity ...

In that experiment, direct current yielded a “sluggish reaction,” whereas rapidly alternating polarity gave total reduction of one of phthalimide’s carbonyl groups under otherwise identical ...
