Hi, I was wondering why the change in bond angle isn't linear for halogenated methane compounds (specifically CH3X where X is the halogen). In the chart, I measured the bond angle between the Halogen-Carbon-Hydrogen and it's not a consistent change. Does this have something to do with Bent's rule (which I do not fully understand)? And what could be the cause for the sudden jump in bond angle for Iodine?
I used MolView to measure the bond angles (and yes I used the energy minimization function)
