H2O@C60 is a remarkable molecule that consists of a polar molecule encapsulated into a highly symmetric and nonpolar cage. For H2O@C60, the polarity is no longer associated with its external shape. The encapsulated water molecule can rotate freely around the center inside the cage. In this ...
Polar organic molecules with longer methylene chains and nonpolar molecules such as dinitrogen and methane were completely excluded. The guest-inclusion properties could be explained by the ion-dipole interaction between the host and the guest, which is proportional to the dipole moment of the guest ...
[49], [50] have proposed a Padé dipolar term that is applied at the segment, rather than molecule level, and has been used by Tumakaka and Sadowski [57] within the perturbed chain SAFT (PC-SAFT) equation to describe mixtures of polar and nonpolar fluids. PC-SAFT has also been ...
Large channels with a polar lining are formed in the crystals of [Phe4,Val6]antamanide, whereas in natural antamanide large channels in the crystal are completely surrounded by the lipophilic side groups of the Pro, Phe, and Ala residues. Antamanide, C64H78N10· 8H2O· X, crystallizes...
Is the H-H bond in hydrogen gas ionic, polar covalent, or nonpolar covalent? Explain. Explain the concept of chemical bonding in chemistry. Briefly explain the polarity of a covalent bond. What do we mean when we say that a bond is a coordinate covalent bond? How ...
