Question
which one is correct
You learned early in the course that valence electrons were key to the physical properties of atoms. This is true for chemical species as well. Lewis/VSEPR diagrams inform chemists of the overall shape of a molecule and the charge distribution (delta^+, delta^-) in 3D space. These are key to understanding a chemical species physical properties. Which of the following statement(s) about the knowledge you gained from Lewis/VSEPR diagrams is/are true? There may be more than one true statements select all true statements for full marks. Molecules with a more overall "linear" shape should be able to interact more effectively with each other. Looking at the bond polarities in a Lewis diagram allows one to determine the direction but not magnitude (strength) of molecular polarity for a chemical species. Significant bond polarities in a Lewis/VSEPR diagram are usually observed in the region of functional groups. Molecules with tetrahedral electronic geometries are always non-polar as the bond dipoles will be equally distributed in 3D space. Looking at the position of functional groups along a chain of carbon atoms may be important in determining overall molecular polarity.Explanation / Answer
- Molecules which are linear, will interact more effectivley --> TRUE
- TRUE, since electrongativity won't allow us to calculate bond force, only attraction
- Bond polarities are usually observed in functional region -- >True
- FALSE, not all tetrahedrical electronic gometries will be nonpolar
- This is true, since the larger it gets, the nonpolar it will get
