QUIZ IN ORGANIC CHEMISTRY
Name of Student: ________________________________________________
Grade and Section: ________________________________________________
SCORE: __________________________
Test I. Identification
Direction: Identify the following and write the correct word on the space provided to complete
the idea.
______________________ 1. It is in the functional group, that carbon is single-bonded to an OH group
(the OH group, by itself, is referred to as a hydroxyl).
______________________ 2. IUPAC
______________________ 3. It is a formula that shows the actual structure of the molecule and gives all
the atoms in a sequential order indicating bonding pattern.
______________________ 4. They structural units within organic compounds that are defined by specific
bonding arrangements between specific atoms.
______________________ 5. It gives the number of carbon atoms present in the parent chain of the
compound and the pattern of their arrangement.
______________________ 6. It is commonly called acetylene, is used as a fuel in welding blow torches.
______________________ 7. This type of formula however does not show the actual bonding pattern
and atom arrangements of the compound.
______________________ 8. It is a useful solvent in the laboratory, and was one of the earlier anesthetic
drugs used in surgery.
______________________ 9. It is characterized by single bonds between carbon and carbon, or
between carbon and hydrogen.
______________________ 10. It represents the substituents or branch present in the parent chain.
