- Dipole moment -
- Disulfide -
- Downfield - A term used to describe the left direction on NMR charts. A peak to the left
of another peak is described as being downfield from the peak.

- E geometry -
- E1 reaction -
- E2 reaction -
- Eclipsed conformation -
- Eclipsing strain -
- Electron - An elementary subatomic particle that carries a negative electrical charge and
occupies an electron shell outside the atomic nucleus. - Electron configuration - The arrangement of electrons in an atom or molecule
- Electron-dot structure -
- Electron shell - The orbit followed by electrons around an atomic nucleus. The atom has
a number of shells and they are normally labelled K, L, M, N, O, P, and Q. - Electronegativity - The ability of an atom to attract electrons towards itself in a covalent
bond. - Electrophile - Literally, electron lover. A positively or neutrally charged reagent that
forms bonds by accepting electrons from a nucleophile. Elecrophiles are Lewis Acids. - Electrophilic addition reaction -
- Electrophilic aromatic substitution -
- Elimination reaction^4 - A reaction where atoms and/or functional groups are removed
from a reactant. - Endergonic - In an endergonic process, work is done on the system, and∆G^0 > 0, so
the process is nonspontaneous. An exergonic process is the opposite: ∆G^0 < 0, so the
process is spontaneous. - Endothermic - An endothermic reaction is a chemical reaction that absorbs heat, and is
the opposite of an exothermic reaction. - Enol - An alkene with a hydroxyl group affixed to one of the carbon atoms composing
the double bond. - Enolate ion -
