Which of the following triatomic ions would you expect to be linear and which would you expect to be V shaped? For those V shaped, suggest approximate bond angles.
(a) BrF2+ ;
(b) BrF2- ;
We are being asked about the molecular geometry of the given compounds, particularly if any of them are linear and/or V-shaped. We are also asked to suggest an approximation of the bond angle for the V-shaped molecule. Aside from these shapes, other possible molecular shapes are:
To do so, we first need to draw a Lewis structure.
For this, we need to do the following steps:
Step 1: Determine the central atom in this molecule.
Step 2: Calculate the total number of valence electrons present.
Step 3: Draw the Lewis structure for the molecule.
Step 4: Determine the shape of the molecule.
