Interpretation: molecular geometry and its importance should be explained.
Concept Introduction: Molecular geometry is the spatial arrangement of the bonded atoms around the central atom. Molecular geometry influences many properties of a molecule.

Explanation of Solution
Explanation 1:
Molecular geometry is the spatial arrangement of atoms on a molecule and/ or ions.
It is the three dimensional arrangement of the bonded atoms with its central atom.
Several chemical and physical properties like polarity, color, reactivity etc. of a molecule depends on its geometry. Even the biological activity of a drug depends on the molecular geometry.
The geometry of a molecule can be found out by different methods like IR, Raman spectroscopy etc.
Here the position of each atom is determined by the nature of
We can predict the geometry by using Lewis structure and VSEPR (Valence-Shell Electron Pair Repulsion) model.
Molecular formula alone is not enough for the prediction of molecular geometry. Type of bonding, lone pair etc. depends on its prediction.
For example, the geometry of a molecule with formula

- Consider the following reactants: Br Would elimination take place at a significant rate between these reactants? Note for advanced students: by significant, we mean that the rate of elimination would be greater than the rate of competing substitution reactions. yes O no If you said elimination would take place, draw the major products in the upper drawing area. If you said elimination would take place, also draw the complete mechanism for one of the major products in the lower drawing area. If there is more than one major product, you may draw the mechanism that leads to any of them. Major Products:arrow_forwardDraw one product of an elimination reaction between the molecules below.
