Substitution Reaction - Substituted Compounds

Substituted compounds are chemical compounds where one or more hydrogen atoms of a core structure have been replaced with a functional group like alkyl, hydroxy, or halogen.

For example benzene is a simple aromatic ring and substituted benzenes are a heterogeneous group of chemicals with a wide spectrum of uses and properties:

compound general formula general structure
Benzene C6H6
Toluene C6H5-CH3
o-Xylene C6H4(-CH3)2
Mesitylene C6H3(-CH3)3
Phenol C6H5-OH

Famous quotes containing the words substituted and/or compounds:

    Verily, the Indian has but a feeble hold on his bow now; but the curiosity of the white man is insatiable, and from the first he has been eager to witness this forest accomplishment. That elastic piece of wood with its feathered dart, so sure to be unstrung by contact with civilization, will serve for the type, the coat-of-arms of the savage. Alas for the Hunter Race! the white man has driven off their game, and substituted a cent in its place.
    Henry David Thoreau (1817–1862)

    We can come up with a working definition of life, which is what we did for the Viking mission to Mars. We said we could think in terms of a large molecule made up of carbon compounds that can replicate, or make copies of itself, and metabolize food and energy. So that’s the thought: macrocolecule, metabolism, replication.
    Cyril Ponnamperuma (b. 1923)
