Polar substances such as urea dissolve because their molecules form hydrogen bonds with the surrounding water molecules. 像尿素这样的极性物质溶解,是因为它们的分子与周围的水分子形成氢键。 HYDROPHOBIC MOLECULES 疏水分子 Substances that contain preponderance of nonpolar bonds are usually insoluble in water an...
[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 ...
Use water as the example. Briefly describe the type of bond: Polar-covalent. Describe the bonding in ethylene, C_2H_4, in terms of valence bond theory. Is a C-H bond ionic or covalent? Explain. Briefly describe the type of bond: Covalent. Why are hydrogen bonds...
Identify the bond that would form between the following pairs of atoms as non-polar covalent, polar covalent, or ionic. a.) Mg and P. b.) Cl and P. c.) I and F. Are the bonds in the compound BrF3 polar covalent, nonpolar covalent, or ...
