Consider SeF4 and XeF4 molecules. In both, the central atom is attached to the same number of Fluorine atoms but have different geometries. Provide an explanation for the different geometries based on the Lewis structure and bond angle measurements

The size (radius) of an oxygen molecule is about 2.0 ×10−10m. make a rough estimate of the pressure at which the finite volume of the molecules should cause noticeable deviations from ideal-gas behavior at ordinary temperatures (t= 300k ). assume that deviatons would be noticeable when volume of the gas per molecule equals the volume of the molecule itself.
