The old adage of like dissolves like comes from understanding the polar or non-polar character of molecules. A molecules polarity rises from the electronegativity of the atoms in the molecule and the spatial positioning of the atoms. Symmetrical molecules are non-polar but as the symmetry of the...

The orientation of molecules is crucial in many chemical processes. Here, we report how single dipolar molecules can be oriented with maximum precision using the electric field of a scanning tunneling microscope. Rotation is found to occur around a fixed pivot point that is caused by the specific...

Water molecules are naturally attracted and stick to each other because of this polarity, forming a hydrogen bond. This hydrogen bond is the reason behind many of water's special properties, such as the fact that it's denser in its liquid state than in its solid state (ice floats on ...

In chemistry, polarity refers to the way in which atoms bond with each other. When atoms come together in chemical bonding, they share electrons. A polar molecule arises when one of the atoms exerts a stronger attractive force on the electrons in the bon
