Xeo4 Bond Angle

The bond angle of the compound XeO4, also known as xenon tetroxide, is approximately 90 degrees. This value is expected based on the molecular geometry of XeO4, which has a tetrahedral shape with four oxygen atoms surrounding the central xenon atom. The repulsion between the electron pairs in the molecule results in a bond angle that is close to the ideal tetrahedral angle of 109.5 degrees but slightly distorted due to the lone pair of electrons on the xenon atom. The presence of this lone pair leads to a slight decrease in the bond angle, resulting in the observed value of approximately 90 degrees.
