Question

How is the molecular geometry different form the electron pair geometry
a. The molecular geometry is based only on the arrangement of atoms, not the arrangement of the electrons
b.The electron pair geometry does not consider the space occupied by the nonbonding pairs of electrons
c. The molecular geometry does not rely on a count of the pairs of electrons but a count of bonded atoms.
d.The molecular geometry and electron geometry are always identical for all molecules

Answer 1

Answer:

a. The molecular geometry is based only on the arrangement of atoms, not the arrangement of the electrons

Explanation:

As we know that molecules geometry is the three dimensional arrangement of molecule.Molecules geometry includes bond angles,bond length ,torsional angle and others parameters which describe the geometry.

When molecules are arrange in proper manner then it is known as molecular geometry and when two lone pairs of electron does not present then it known as electronic geometry.

So the option a is correct.

a. The molecular geometry is based only on the arrangement of atoms, not the arrangement of the electrons

Answer 2

Answer:

The correct answer is option c.

Explanation:

Molecular geometry is defined as three dimensional arrangement of the atoms constituting the molecule in a space. It gives us picture of the shape of the molecule , its bond lengths, bond angles and other parameter related to it which tell us about the positions of the atoms.

Electron pair geometry is defined as three dimensional arrangement of the electrons around the central atoms. Or it can also be define as arrangement of atoms and lone pair in three dimensional space which along position of atoms also tells the us the position of lone pairs.
