CH 301 Study Guide - Quiz Guide: Vsepr Theory, Chemical Polarity, Sigma Bond
Document Summary
Question types notes for quiz #2 (chem) (lecture 10-12) Identifying ionic and covalent bond in polar and non-polar molecules. Ex: na-----cl: vsepr: assigning bond angle to a lewis structure [see next page, vsepr: assigning hybridization to a lewis structure [see next page, vsepr: assigning electronic geometry to a lewis structure [see next page] Electronic geometry the shapes of the electron rich regions. Erase the atoms and just look at the electron pairs and the five possible answers: vsepr: assigning molecular geometry to a lewis structure [see next page] Molecular geometry 13 possible shapes of the atoms in the molecule and ignores the electrons. Erase the electrons and just look at the shape the atoms take on. All hybrids form sigma bonds: vb: identifying the atomic orbitals that create a sigma or pi bond. An overlap of e- density from 2 atomic orbits. Dipole moment a vector describing the orientation of electron density.
