CHM 219 Module 4 Exam Questions And
Answers 2025 Update.
Organohalides - Answer✔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 types typical of organic Halides are.... -
Answer✔Substitution
Elimination
Substitution Reaction - Answer✔Replacing the halogen in a molecule with another atom or
functional group.
Elimination - Answer✔Removes the halogen and hydrogen atoms from the original substrate
molecule creating an unsaturated compound.
Alkyl halide - Answer✔Aliphatic hydrocarbons that possess one or more halogen atom
substituents.
Aryl Halides - Answer✔Aromatic hydrocarbons (benzene rings) with one or more halogen
atoms attached to the ring.
Steric Bulk - Answer✔Structural substitution surrounding any carbon atom that bears a
halogen. Methyl, primary, secondary, tertiary.
Primary Alkyl Halide - Answer✔Only on e carbon is directly attached to the carbon bearing the
halogen.
Secondary Alkyl Halid - Answer✔Two carbons directly attached to the carbon ring bearing the
halogen
Tertiary Alkyl Halide - Answer✔Three carbons are directly attached to the carbon bearing the
halogen
Methyl halide - Answer✔Only hydrogen atoms attached to the carbon bearing the halogen
