Definition
| The lowest energy orbital is filled first |
|
|
Term
| Pauli exclusion principal |
|
Definition
| Each orbital can accommodate a max of 2 electrons that have opposite spins |
|
|
Term
|
Definition
| Dealing with degenerate orbitals such as p orbitals one election is placed in each degenerate orbital first, before electrons are paired up |
|
|
Term
|
Definition
| Overlap of 1s orbital. All sigma bonds are sigma bonds |
|
|
Term
|
Definition
| VAlence shell electron pair repulsion theory. Electrons are as far away from each other as possible. |
|
|
Term
|
Definition
| In order to predict the geometry of a small compound, small compound, we focus on the central atom and count the number of sigma bonds AND lone pairs. The total is the steric number. |
|
|
Term
|
Definition
| Must use 4 orbitals - sp3 hybridized. Tetrahedral. (if no lone pairs=tetrahedral) if one lone pair= trigonometry pyramidal. (two lone pairs--bent) |
|
|
Term
|
Definition
| Sp2 hybridized ( double bonds) if one lone pair it's bent, if none then it's trigonal planar |
|
|
Term
|
Definition
|
|
Term
|
Definition
| Sp2. has 2 bonding interactions, 1 sigma and 1 pi bond. |
|
|
Term
|
Definition
| Sp. Has three bonding interactions, one sigma and two pi bonds. |
|

|
|
Term
| Difference in electronegativity values greater than 1.7 |
|
Definition
|
|
Term
| Dipole dipole interactions |
|
Definition
| Electronegativity difference between atoms in a molecule. Attraction between molecules results in an elevated melting and boiling point |
|
|
Term
|
Definition
| Protic compounds- proton connected to an electronegative atom. More hydrogen bonds- higher boiling point |
|
|
Term
| Fleeting dipole dipole interactions |
|
Definition
| Hydrocarbons- boiling point increases with molecular weight |
|
|
Term
|
Definition
| Cause decrease in boiling point. |
