MO + VSEPR Theory
While O2 is paramagnetic, this homonuclear diatomic molecule from the second period is predicted by MO theory to be diamagnetic with a bond order of 2.
What is C2
The hybridization of the central atom in a molecule with two electron domains and 180° bond angles.
What is sp hybridization
Among molecules of similar size, the one with stronger intermolecular forces will have this higher physical property
What is boiling point
The phase transition that occurs when vapor becomes liquid
What is condensation
This rule states that atoms tend to gain, lose, or share electrons until they are surrounded by eight valence electrons.
What is the Octet rule
According to VSEPR theory, lone pairs are physically larger than bonding pairs. This explains why the bond angle in Ammonia (NH3) is 107° rather than this "ideal" tetrahedral angle.
What is 109.5°
The number of hybrid orbitals formed when 10 atomic orbitals mix
What is 10 hybrid orbitals
Strongest type of Dipole-Dipole interaction
What is Hydrogen Bonding
The boiling point of a liquid is when the atmospheric pressure matches the liquid's...
What is Vapor pressure
This is the calculated charge an atom would have if all bonding electrons were shared equally between the bonded atoms.
What is a formal charge
for Period 2 diatomic molecules such as N2, a specific bonding orbital which is higher in energy than pi 2p orbitals is formed
What is the sigma 2p orbital
An atom having sp hybridization has this number of hybrid orbitals and this geometry
What are two hybrid orbitals and linear geometry
London Dispersion Forces (LDFs) increase primarily with increasing size of the electron cloud because of this property.
What is polarizability
The point where solid, liquid, and gas coexist in equlibrium
What is a triple point
This phenomenon occurs when two or more valid Lewis structures can be drawn for a single molecule, such as Ozone
What is Resonance
In a Trigonal Bipyramidal system (like PCl5), VSEPR theory dictates that larger substituents or lone pairs will always occupy these positions to minimize 90° repulsions.
What are equatorial positions?
This concept explains why all Carbon-Carbon bonds in Benzene are of equal length, involving the overlap of p orbitals across the entire ring.
What is pi delocalization
This term describes the resistance of a liquid to flow, which increases as the strength of IMFs increase and temperature decreases.
What is Viscosity?
Beyond this specific point on a phase diagram, the distinction between liquid and gas disappears
What is the Critical Point?
This is the formal charge of the central Iodine atom in the I3- ion
What is -1
According to VSEPR, this molecular geometry is adopted by SF6 where all bond angles are 90°
What is Octahedral
An atom with 3 lone pairs and 2 bonds has this hybridization state and shape
What is Sp3d and linear
This is the term for the energy required to increase the surface area of a liquid by a unit amount, resulting from the net inward force on surface molecules.
What is Surface Tension?
This equation relates the vapor pressure of a liquid to its temperature and enthalpy of vaporization (𝚫Hvap)
What is the Clausius-Clapeyron Equation
This number of resonance structures can be drawn for the molecule NO3-
What is 3
