Homework Help: Bond angles

  1. Oct 20, 2008 #1
    How is the bond angle for Cl-C-Cl in dichloromethane different from H-C-H bond angle of CH4? Is it smaller??

    What is the size of Cl vs. H in your examples?

    Chlorine has three free electron pairs, hydrogen has none. Because of the electon pairs chlorine atoms repell from each other more strongly so the Cl-C-Cl bond angle should be bigger than H-C-H. Im not sure of this, but it seemed logical to me.
