Question

PART A: Group the following molecular formulas under their respective geometries. Use the Real Molecules mode to verify the correct geometry for select structures.

PART B: For each type of geometry in the simulation, examine the resulting bond angles by clicking the Show Bond Angles checkbox. Based on your observations for each geometry, provide the bond angles at the indicated locations. Express the bond angles in degrees. Complete all fields.

Answer 1

Concepts and reason

Determine the electron domain geometry of the molecule based on the number of electron pairs around the central atom.

First find out number of atoms present around the central atom of a molecular geometry, then identify the possible shape of the geometry. Finally indicate possible number of different number of electron-domain geometries that are consistent with the molecular geometry.

Predict the bond angles to the molecular geometries based on the shape.

Fundamentals

Electron pairs that are not involved in the bond formation are called as lone pairs. Pair of electrons that involved in the bonding are called as bond pairs. Number of atoms around the central atom is equal to number of bond pairs.

Geometries of the molecules are as follows:

Molecular geometry of the molecule is triangular planar.

The molecule has octahedral geometry.

Molecular geometry of the molecule is linear.

Molecular geometry of is linear.

Molecular geometry of the molecule is tetrahedral.

Molecular geometry of the molecule is trigonal bipyramidal.
