Hey Guys!
i was wondering what would be the bond angle of FXe2..would it be 104.5 or 90?
thanx

The FXe2 bond angle of 104.5° refers to a linear structure, where two fluorine atoms are directly bonded to a central xenon atom. In this arrangement, the bond angle is slightly bent due to the repulsion between the lone pairs of electrons on the xenon atom. On the other hand, a bond angle of 90° indicates a square planar structure, where the four atoms (two fluorine and two lone pairs) are arranged at right angles to each other.
The bond angle of 104.5° occurs due to the repulsion between the lone pairs of electrons on the central xenon atom. These lone pairs take up more space in the molecule, causing the bond angles to be slightly bent from the ideal linear angle of 180°.
The main factor that influences the FXe2 bond angle is the repulsion between the lone pairs of electrons on the central xenon atom. Other factors that may play a role include the electronegativity of the atoms involved, the size of the atoms, and the overall molecular geometry.
The FXe2 bond angle can affect the properties of the molecule in various ways. For example, a bent bond angle can result in a polar molecule, as the electronegative fluorine atoms will have a greater pull on the shared electrons. This can lead to differences in the molecule's reactivity, polarity, and physical properties such as boiling and melting points.
Yes, the FXe2 bond angle can change in different chemical environments. This can occur due to different factors, such as the presence of other atoms or molecules that may interact with the molecule, or changes in temperature and pressure. These changes can alter the repulsion between the lone pairs of electrons and affect the overall bond angle in the molecule.
