Organohalides Organic molecules contains Halogen atoms.
Ex. Algae, Mollusk, sponges, can be industrially
used - solvents, insecticides, herbicides, cleaning
fluids, fire retardants, refrigerants. Can also be
used as inhaled anesthetic.
More important in organic chemistry because of
theur reactivity.
Two of the most important reaction Substitution
types typical of organic Halides Elimination
are....
Substitution Reaction Replacing the halogen in a molecule with another
atom or functional group.
Elimination Removes the halogen and hydrogen atoms from
the original substrate molecule creating an
unsaturated compound.
Alkyl halide Aliphatic hydrocarbons that possess one or more
halogen atom substituents.
, Aryl Halides Aromatic hydrocarbons (benzene rings) with one
or more halogen atoms attached to the ring.
Steric Bulk Structural substitution surrounding any carbon
atom that bears a halogen. Methyl, primary,
secondary, tertiary.
Primary Alkyl Halide Only on e carbon is directly attached to the
carbon bearing the halogen.
Secondary Alkyl Halid Two carbons directly attached to the carbon ring
bearing the halogen
Tertiary Alkyl Halide Three carbons are directly attached to the
carbon bearing the halogen
Methyl halide Only hydrogen atoms attached to the carbon
bearing the halogen
X Symbol for generic halogen
Polarization of C-H bond Carbon will be electron-deficient and thus hold a
slight positive charge and slight negative charge
on the halogen
Nucleophilic substitution reaction Halogen is replaced (substituted by) a new atom
or functional group.
Abbreviated Sn
Functional Group Interconversion When one type of functional group (alkyl halide)
is converted to another by substitution.
Substrate Molecule on which the substitution occurs.
