Answer:
eg=linear, mg=linear
Explanation:
First of all, it must be stated that most triatomic molecules are either linear or bent. This depends on the electron geometry of the molecule and the number of bonding groups, multiple bonds and lone pairs present.
CO2 contains four regions of electron density and two bonding groups. For a specie containing two bonding groups, a linear molecular geometry is expected with an angle of 180°.
For a specie having two bonding groups and no lone pairs with multiple bonds, the expected electron geometry is also linear.
CO₂ has a linear electron geometry and a linear molecular geometry. The correct option is the second option - eg=linear, mg=linear
From the question,
We are to determine the electron geometry and molecular geometry of CO₂.
First we will define some terms
Electron geometry is the arrangement of electron groups around the central atom of a molecule
NOTE: A lone pair, single, double, or triple bond represents one electron group.
Molecular geometry refers to the arrangement of atoms in a molecule.
CO₂ has 2 double bonds surrounding the central atom. This means CO₂ has 2 electron groups. A molecule with 2 electron groups will have a linear electron geometry.
CO₂ has 2 pairs of bonding electrons around the central atom at an angle of 180°. Therefore CO₂ has a linear molecular geometry.
Hence, CO₂ has a linear electron geometry and a linear molecular geometry. The correct option is the second option - eg=linear, mg=linear
