Sure! I'd be happy to check your answers and explain the interparticle force of attraction.
Let's go through each compound one by one:
1. Chlorine (Cl2):
- Chemical formula: Cl2
- Name: Chlorine
- Bond Type (intermolecular FOA): London dispersion forces (also known as van der Waals forces or dispersion forces).
- VSEPR molecular shape: Tetrahedral (This is not applicable for diatomic molecules like Cl2, as the VSEPR theory is designed for molecules with more than two atoms).
- Central Atom Hybridization: sp3 (This is not applicable for diatomic molecules like Cl2).
- Molecular Polarity: Nonpolar (Since the two chlorine atoms have the same electronegativity, the electron density is evenly distributed leading to a nonpolar molecule).
- Interparticle force of attraction (IPFOA): London dispersion forces. In the case of Cl2, the intermolecular forces (IMF) are caused by temporary shifts in electron density that induce dipole moments. These temporary dipoles attract neighboring Cl2 molecules, creating London dispersion forces.
- State of Matter (at room temperature): Gas
2. Dihydrogen oxide (H2O):
- Chemical formula: H2O
- Name: Water
- Bond Type (intermolecular FOA): London dispersion forces, dipole-dipole interactions, and hydrogen bonding.
- VSEPR molecular shape: Bent (or V-shaped)
- Central Atom Hybridization: sp3
- Molecular Polarity: Polar (Due to the bent geometry and the electronegativity difference between hydrogen and oxygen, the water molecule has a permanent dipole moment.)
- Interparticle force of attraction (IPFOA): In the case of H2O, the interparticle forces are London dispersion forces, dipole-dipole interactions between neighboring water molecules, and hydrogen bonding, which is a special type of dipole-dipole interaction. Hydrogen bonding occurs when the hydrogen atom of a water molecule bonds to the highly electronegative oxygen atom of a neighboring water molecule.
- State of Matter (at room temperature): Liquid
3. Sodium (Na):
- Chemical formula: Na
- Name: Sodium
- Bond Type (intermolecular FOA): London dispersion forces
- VSEPR molecular shape: None (This is not applicable for elements like sodium that exist as individual atoms).
- Central Atom Hybridization: sp (This is not applicable for elements like sodium that exist as individual atoms).
- Molecular Polarity: Nonpolar (Since the sodium atom doesn't have a permanent dipole moment due to its low electronegativity).
- Interparticle force of attraction (IPFOA): In the case of sodium, the interparticle forces are governed by London dispersion forces. Since sodium atoms exist as separate entities, the intermolecular forces are between individual sodium atoms, resulting from temporary shifts in electron density that induce dipole moments.
- State of Matter (at room temperature): Solid
4. Sodium chloride (NaCl):
- Chemical formula: NaCl
- Name: Sodium chloride
- Bond Type (intermolecular FOA): London dispersion forces, dipole-dipole interactions, and ion-dipole interactions.
- VSEPR molecular shape: None (This is not applicable for ionic compounds like NaCl which do not have discrete molecules)
- Central Atom Hybridization: sp3 (This is not applicable for ionic compounds like NaCl which do not have discrete molecules)
- Molecular Polarity: Polar (Due to the electronegativity difference between sodium and chlorine, the bond in NaCl is polar)
- Interparticle force of attraction (IPFOA): In the case of NaCl, the interparticle forces are London dispersion forces, dipole-dipole interactions (between polar molecules), and ion-dipole interactions (between ions and polar molecules). In NaCl, the positively charged sodium ions and negatively charged chloride ions attract each other, resulting in ionic bonds.
- State of Matter (at room temperature): Solid
Please note that intermolecular forces refer to the forces between molecules, while interparticle forces of attraction refer to the forces between particles in a substance, which can include molecules, atoms, or ions.
