CHM 219 Module 4
Organ halides - answerOrganic 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 types typical of organic Halides are.... -
answerSubstitution
Elimination
Substitution Reaction - answerReplacing the halogen in a molecule with another atom
or functional group.
Elimination - answerRemoves the halogen and hydrogen atoms from the original
substrate molecule creating an unsaturated compound.
Alkyl halide - answerAliphatic hydrocarbons that possess one or more halogen atom
substituents.
Aryl Halides - answerAromatic hydrocarbons (benzene rings) with one or more halogen
atoms attached to the ring.
Steric Bulk - answerStructural substitution surrounding any carbon atom that bears a
halogen. Methyl, primary, secondary, tertiary.
Primary Alkyl Halide - answerOnly on e carbon is directly attached to the carbon bearing
the halogen.
Secondary Alkyl Halid - answerTwo carbons directly attached to the carbon ring bearing
the halogen
Tertiary Alkyl Halide - answerThree carbons are directly attached to the carbon bearing
the halogen
Methyl halide - answerOnly hydrogen atoms attached to the carbon bearing the halogen
X - answerSymbol for generic halogen
Polarization of C-H bond - answerCarbon will be electron-deficient and thus hold a slight
positive charge and slight negative charge on the halogen
