100
This model states that electron domains are arranged in a way such as that the repulsion among the domains is minimized.
What is VSEPR theory? (YC)
100
This process allows an electron from an s orbital to mix with an electron from the p orbital.
What is hybridization? (YC)
100
This term describes a property of a molecule that is strongly attracted to magnetic field.
What is paramagnetism? (DJ)
100
This is a bond formed by end-to-end overlap of two orbitals.
What is a sigma bond? (DY)
100
This is the quantitative representation of polarity.
What is dipole moment? (JB)
200
This is the molecular geometry of ICl_4(-).
What is square planar? (JB)
200
According to this model, a linear arrangement of electron domains implies sp hybridization.
What is valence-bond model? (YC)
200
In the bonding molecular orbital in H_2, the electrons are located here so that it is more stable.
What is internuclear axis? (YC)
200
The triple bond contains this many sigma bond(s) and this many pi bond(s).
What is one sigma bond and two pi bonds? (DJ)
200
These are the seven nonpolar diatomic atoms.
What is H_2/N_2/O_2/F_2/Cl_2/Br_2/I_2? (DY)
300
This is the exact bond angle of H_2O.
What is 104.5 degrees? (DY)
300
This describes the hybridization of the organic molecule C_6H_6.
What is sp^2 hybridization? (JB)
300
This is why H_2 electrons are more stable than an electron in a hydrogen atom.
What is completed σ_1s orbital? (YC)
300
This is the hybridization of boron and fluorine that yields three BF_3.
What is sp^2? (DY)
300
This is the direction the dipole moment points in the molecule XeF_2.
What is there is no dipole moment? (DJ)
400
This is why the unbonding pairs are located at the equatorial plane for trigonal bipyramidal.
What is it minimizes the electron to electron repulsion since the unshared pair to unshared pair repulsion is greater than the shared pair to unshared pair? (DJ)
400
This is when electrons are spread out over a number of atoms instead of confined to a pair of atoms.
What is delocalization? (DY)
400
This is the highest level molecular orbital for for molecules B_2 through Ne_2.
What is σ*_2p? (JB)
400
Carbon has an electron configuration of [He](2s^2)(2p^2). If hybridization occurs, an electron is "promoted" from s to p orbital, creating sp^3 overall. Yet, the carbon in C_2H_2 has a hybridization of sp. The remaining two p unhybridized orbital allows THIS to happen in C_2H_2.
What is allowing the two pi bonds in the triple bond in C_2H_2 to form? (YC)
400
This is the charge of a F atom in a ClF molecule with µ=0.88D and a bond length of 1.63Å, given in units of e- charge.
What is -0.11e? (JB)
500
This is the reason for considering double or triple bonds as one electron domain.
What is the pi bonds do not affect the property of direction of the sigma bond because the sigma bonds are parallel to the pi bonds? (DJ)
500
This is the hybridization of the carbon of a molecule that contains 14.4% of H and 85.6% of C with a molar mass of 28.1 g/mol.
What is sp^2? (DJ)
500
This is the formula of a diatomic molecule of oxygen with a bond order of three halves.
What is superoxide? (DY)
500
This is the change in enthalpy for CO+Cl_2 --> COCl_2, given D(C≡O)=1672 kJ/mol, D(Cl-Cl)= 242 kJ/mol, D(C=O)= 799 kJ/mol, and D(C-Cl)= 328 kJ/mol.
What is -141 kJ/mol? (JB)
500
If a molecule is simplified into two opposing charges, the electric force between the two charges Q and -Q under distance R is E. Under this situation, the dipole moment exists with this VALUE, described using E, R, and K, Coulomb's constant.
