Study Notes
Electron Energy and Location
- Electron energy increases with distance from the nucleus.
Suborbital Quantum Number (l)
- Represents the region where an electron is most likely to be found.
- Suborbital shapes and sizes vary based on energy level.
Group VIA and VIIA Elements
- Elements in Group VIA and VIIA often gain electrons to form anions.
- Forming an anion creates a filled p orbital configuration, resembling the inert gas in the same period.
- Examples include oxygen and bromine.
Water Molecule and Bond Angle
- Formation of covalent bonds between hydrogen and oxygen in water.
- Expected H-O-H bond angle is 180 degrees if the hydrogen atoms bond through specific orbitals.
Coordinate Covalent Bonding
- A covalent bond where both electrons originate from one atom's orbital.
- Commonly found in complex chemical entities.
Bonding in CO2
- Both electrons could be removed from the 3d orbital, leading to a rearrangement of all valence electrons.
- Each C—O bond consists of two pairs of electrons.
- Sigma bonds are formed by overlapping sp orbitals on the carbon with singly occupied p orbitals on the oxygens.
- Oxygen atoms can be rotated to bring their p orbitals parallel to a carbon p orbital.
- Overlapping of parallel p orbitals on carbon and oxygen forms two volumes of electron density separated by a nodal plane.
- This results in the formation of a pi bond between the carbon and each oxygen.
Triple Bond
- Hydrogen cyanide (HCN) serves as an example of a molecule with a triple bond.
- Two pi bonds are formed between the carbon and nitrogen atoms in HCN.
- The carbon is sp-hybridized, similar to CO2.
- Both p orbitals on the carbon overlap with two p orbitals on the nitrogen.
Nonpolar Intermolecular Forces
- Van der Waals forces are the primary attractive forces between nonpolar molecules.
- These forces are responsible for the association between aromatic hydrocarbon molecules like benzene.
