CHEM219 Module 4 Questions and Correct
Answers/ Latest Update / Already Graded
Halogen atoms
Ans: F, Cl, Br, I
organohalide in marine life
Ans: adapted to environment by metabolizing the high
concentrations of inorganic chlorides and bromides that are
found in the seas (ex: algae, mollusks, sponges)
industrial organohalides
Ans: solvents, insecticides, herbicides, cleaning fluids, fire
retardants, refrigerants
Teflon
Ans: polymer containing carbon-fluorine bonds instead of
carbon-hydrogen bonds; found as lubricant and in non -stick
cookware
Why are halogen-containing compounds important in organic
chemistry?

Ans: Because of their reactivity
-can be used as starting materials in the synthesis of larger and
more complex organic molecules because of the variety of
reactions that can occur in an organohalide
Substitution organohalide
Ans: replacing the halogen atom in a molecule with another
atom or functional group
elimination organohalide
Ans: reaction that removes the halogen and hydrogen atoms
from original substrate molecule creating an unsaturated
compound
alkyl halides
Ans: aliphatic hydrocarbons that possess one or more halogen
atom substituents (form one single covalent bond like hydrogen
atoms)
Aryl halides
Ans: aromatic hydrocarbons (benzene rings) with one or more
halogen atoms attached to the ring
