Comparing Intermolecular Forces: Melting Point, Boiling Point, and Miscibility

44.0K
Intermolecular forces are attractive forces that exist between molecules. They dictate several bulk properties, such as melting points, boiling points, and solubilities (miscibilities) of substances. Molar mass, molecular shape, and polarity affect the strength of different intermolecular forces, which influence the magnitude of physical properties across a family of molecules.
Temporary attractive forces like dispersion are present in all molecules, whether they are polar or nonpolar. They...

Radical Chain-Growth Polymerization: Chain Branching

1.9K
The skeletal structure of polymers synthesized via radical polymerization is always branched. For example, the polymerization of ethylene by radical polymerization results in a low-density grade of polyethylene with a heavily branched skeletal structure. Here, the radical site abstracts hydrogen from the growing chain, and the radical site shifts from the end (a primary carbon center) to anywhere within the growing chain (a secondary carbon center). Consequently, the part of the chain from the...

Solution Formation

31.4K
There is no one solvent that can dissolve every type of solute. Some substances that readily dissolve in a certain solvent might be insoluble in a different solvent. A simple way to predict which substances dissolve in which solvent is the phrase "like dissolves like". This means that polar substances, such as salt and sugar, dissolve in a polar substance like water. In contrast, non-polar substances are more soluble in non-polar solvents such as carbon tetrachloride.
This selective...

Polymer Classification: Stereospecificity

2.4K
Polymerization generates chiral centers along the entire backbone of a polymer chain. Accordingly, the stereochemistry of the substituent group has a significant effect on polymer properties. Polymers formed from monosubstituted alkene monomers feature chiral carbons at every alternate position in the polymer backbone. Relative to the predominant orientation of substituents at the adjacent chiral carbons, the polymer can exist in three different configurations: isotactic, syndiotactic, and...

Area of Science:

  • Physical Chemistry
  • Polymer Science
  • Solution Chemistry

Background:

  • Understanding solute transport in solutions is crucial for chemical processes.
  • Hydrodynamic models provide theoretical frameworks for predicting molecular motion.
  • Accurate prediction of translational diffusion constants (D) is essential for characterizing solute behavior.

Purpose of the Study:

  • To evaluate a hydrodynamic bead model based on Kirkwood-Riseman theory for calculating translational diffusion constants.
  • To compare model predictions with experimental data for diverse solute-solvent systems.
  • To assess the model's applicability and limitations, particularly concerning solvent properties like hydrogen bonding.

Main Methods:

  • Utilized a hydrodynamic bead model derived from Kirkwood-Riseman theory.
  • Calculated translational diffusion constants (D) for polymethylene chain solutes.
  • Compared calculated D values with 102 experimental values across various polar and nonpolar solvents.

Main Results:

  • Achieved an average absolute percentage difference of approximately 3% between experimental and calculated diffusion constants.
  • The model demonstrated good agreement for n-alkanes in polar solvents and primary alcohols in nonpolar solvents.
  • Adjustments for solvent aggregation due to hydrogen bonding were necessary for n-alkanes in 1-octanol; poor agreement was observed for primary alcohols in 1-octanol due to solute-solvent hydrogen bonding.

Conclusions:

  • The hydrodynamic bead model provides a reliable method for predicting translational diffusion constants.
  • The model's accuracy is high for many solute-solvent combinations, but limitations exist for systems with significant solute-solvent hydrogen bonding.
  • Alternative correlations based on molar volume showed poorer agreement than the bead model.
