I believe it depends on the identity of the outer atom

Well, if all the electron groups around a central atom are bonding, I would say the molecule is quite popular! Just like a catchy tune that everyone likes. But whether it's polar or nonpolar, that's a different story. It all depends on the identity of the outer atom, kind of like how it depends on who you take to prom. Some atoms are just more electronegative than others and hog that electron love, making the molecule polar. Others are more laid-back and share the electrons equally, making the molecule nonpolar. So, it's like a chemistry dance party where the outer atom brings the vibes and sets the mood for polarity.

1. The molecular geometry around a single central atom is the same as the electron group geometry when there are no lone pairs present on the central atom. This means that all the electron groups around the central atom are bonding pairs.

2. If all of the electron groups around a single central atom are bonding and the same outer atom is bonded to the central atom in each case, the molecule will be nonpolar. This is because when all the surrounding electron groups are bonding, they pull on the central atom equally in all directions, resulting in a symmetrical distribution of charge. This symmetrical distribution cancels out any net dipole moment, making the molecule nonpolar.

Therefore, in this case, the polarity of the molecule does not depend on the identity of the outer atom, as long as all the electron groups are bonding.

1. Under what circumstances is the molecular geometry around a single central atom the same as the electron group geometry around the central atom?

The molecular geometry refers to the spatial arrangement of atoms around a central atom in a molecule, while the electron group geometry refers to the spatial arrangement of electron groups (bonding and non-bonding) around the central atom. In some cases, the two geometries can be the same. This happens when all of the electron groups around the central atom are bonding, meaning they are involved in the formation of chemical bonds.

For example, in a molecule like carbon dioxide (CO2), the central atom (carbon) is surrounded by two bonding electron groups (covalent bonds with oxygen atoms) and no non-bonding electron groups. The bonding electron groups repel each other, causing the molecule to assume a linear molecular geometry. The electron group geometry (linear) and molecular geometry (also linear) are the same in this case.

2. If all of the electron groups around a single central atom are bonding, and the same outer atom is bonded to the central atom in each case, is the molecule polar, nonpolar, or does it depend on the identity of the outer atom?

In this scenario, whether the molecule is polar or nonpolar depends on the identity of the outer atom.

If the outer atom is symmetrical, meaning it has similar electronegativity and the same arrangement of atoms around it, the molecule will be nonpolar. This is because the polar bonds cancel out each other's effects, resulting in a balanced distribution of charge throughout the molecule.

On the other hand, if the outer atom is asymmetrical, meaning it has different electronegativity or an unequal arrangement of atoms around it, the molecule will be polar. This is because the polar bonds do not cancel out each other's effects, leading to an uneven distribution of charge in the molecule.

To determine whether the molecule is polar or nonpolar, you can consider the symmetry of the molecule and the difference in electronegativity between the central atom and the outer atom. If the molecule is symmetrical or there is no significant difference in electronegativity, the molecule is likely to be nonpolar. However, if the molecule is asymmetrical or there is a substantial difference in electronegativity, the molecule is likely to be polar.

1. When there are no lone pairs of electrons (no non-bonding electrons).

2. I don't make head or tails of the question.
