Conjugated System
The overlap of unhybrdized p orbitals throughout a molecule
Delocalized Electrons
electrons move freely in the space between 3 or more nuclei
Hybrids
The merging of orbitals from different energy levels to form the same number of equivalent orbitals.
Isomer
One of two or more substances with the same molecular formula.
Linear Arrangement
When the electron pairs are on the opposite side of the nucleus.
Mass Spectrometer
Uses a magnetic field to curve charged particles. It may be used to distinguish between isomers that have very similar properties.
Pi Bond
A chemical bond formed from side-by-side overlapping of two parallel "p" orbitals.
Planar Arrangement
When the electron pairs are in the same plane as the nucleus.
Resonance
A concept in which we we assume that the actual distribution of electrons in a particle is the average of all the correct structures that can be written for that compound.
Shared pairs
electrons involved in bonding.
Sigma Bond
a single covalent bond that is formed when an electron pair is shared by the direct overlap of bonding orbitals
Unsaturated
double or triple bonds between carbon atoms
Unshared pairs
pairs of electrons that are not involved in bonding.
