Organic Chemistry
Exam 1 Terms
Term | Definition |
---|---|
constitutional isomers | share the same molecular formula but have different connectivity of atoms and different physical properties. |
covalent bond | results when two atoms share a pair of electrons |
octet rule | bonding to achieve noble gas electron configuration |
lone pair | a pair of unshared electrons |
formal charge | occurs when atoms do not exhibit the appropriate number of valence electrons |
induction | what polar covalent bonds exhibit that cause the formation of partial positive charges and negative charges |
electrostatic potential maps | present a visual illustration of partial charges |
quantum mechanics | describes electrons in terms of their wavelike properties |
wave equation | describes total energy of an electron when in the vicinity of proton |
wave functions | solutions of a wave equation that represents the probability of finding an electron in a particular location. |
atomic orbitals | represented visually by generating three-dimensional plots; nodes indicate that the value is zero |
valence bond theory | treats every bond as the sharing of electron density between two atoms as a result of the constructive interference of their atomic orbitals |
sigma bonds | formed when the electron density is located primarily on the bond axis |
molecular orbital theory | uses a mathematical method called the linear combination of atomic orbitals to form molecular orbitals |
atomic orbital | a region of space associated with an individual atom |
