Ans: The structure of XeF2 is linear. In this Xe acts as a central atom and two Fluorine are attached to Xe. They are on the opposite sides of each other forming a straight line. The hybridization of XeF2 is sp3.
The structure of NH3 is pyramidal molecular geometry. Nitrogen is at the tip of the pyramid with three hydrogen atoms at the base of the pyramid. The bond angle in NH3 is 107 degrees, the angle is less due to lone pair bond pair repulsion. The hybridization of NH3 is sp3.
The correct increasing order for bond angles among \( \text{BF}_3, \, \text{PF}_3, \, \text{and} \, \text{CF}_3 \) is:
The Valence Shell Electron Pair Repulsion Theory abbreviated as VSEPR theory is based on the premise that there is a repulsion between the pairs of valence electrons in all atoms, and the atoms will always tend to arrange themselves in a manner in which this electron pair repulsion is minimalized.
