Does aromaticity cause hydrophobic
Webcloud of the aromatic bases is extremely important. Therefore, stacking requires aromaticity of the bases-nonaromatic bases do not display stacking interactions. The strength of stacking interactions depends on how polarizable the p electron cloud of a base is. This in turn depends on the - withdrawing or donatinge potential of the base ... Web13.19: The Effect of Conjugation on λmax. While interaction with infrared light causes molecules to undergo vibrational transitions, the shorter wavelength, higher energy radiation in the UV (200-400 nm) and visible (400-700 nm) range of the electromagnetic spectrum causes many organic molecules to undergo electronic transitions.

WebStacking (chemistry) In chemistry, pi stacking (also called π–π stacking) refers to the presumptive attractive, noncovalent pi interactions ( orbital overlap) between the pi bonds of aromatic rings. However this is a misleading description of the phenomena since direct stacking of aromatic rings (the "sandwich interaction") is ... WebCauses of water repellence.
