100
Most single bonds are these - H
What are sigma bonds
200

What is Tetrahedral and 104.5 degrees
200
This theory dictates how orbitals overlap in covalent bonding - K
What is valence-bond theory
200
The dipole moment and dipole moment are which quantities? - S
What are vector quantities
200
Bond order of 0 represent this type of bonding - S
What is No bonding. (does not exist)
200
How many pi bonds are in most triple bonds - H
What is 2
300
What is the molecular geometry of Boron trifluoride, does the central atom obey the octet rule? - P
What is Trigonal Planar, no
300
This type of hybrid orbital is common to trigonal planar geometries - K
What is sp^2 hybridization
300
Why does a Cl-Cl bond not have a dipole moment? - H
What is the difference in Electronegativity = 0
300
This type of molecule has one or more unpaired electrons in a magnetic field - S
What is paramagnetic molecule
300
Rank in order of increasing Bond Strength: H_2, N_2, and O_2 - H
What is H_2 < O_2 < N_2
400
What is the electron domain geometry and molecular geometry of XeF_4? - P
What is Octahedral and Square Planar
400
This type of hybrid orbital forms in BrF_3 molecules - K
What are sp^3d orbitals
400
The dipole moment depends on which two properties of the molecule? - S
What are polarities of individual bonds and geometry of the molecule
400
When an electron pair with another electron before all molecular orbitals of same energy is occupied, this rule is violated. - S
What is Hund’s rule
400
What causes the delocalization of electrons - H
What is electrons are “smeared out” among the atoms in molecules with 2 or more resonance structures, because the pi bonds in these structures cannot be described as individual electron bonds
500
This electron pair only exists on the equatorial domain of trigonal bipyramidal geometries. Why? - K
What is a nonbonding pair, because equatorial domains experience less repulsion than axial domains (90 degrees from two other domains < 90 degrees from three other domains)
500
These atoms are the only ones that form trigonal bypriamidal and octahedral EDGs. Why? - K
What are third period and beyond atoms? They possess vacant d orbitals to hybridize and form sp^3d and sp^3d^2 orbitals
500
For AB4 molecules in which all the B atoms are the same, what are the symmetrical shapes must lead to nonpolar molecules regardless of polarity of individual bonds? - S
What are Tetrahedral and Square Planar
500
These diatomic molecules have Sigma 2p MO at higher energy than pi 2p MO - S
What are B2, C2, and N2
500
How are electrons distributed in pi bonds - P
What is p orbitals overlap sideways, electrons are found near the overlap zone, no possibility of finding them on the internuclear axis.
