Organic Chemistry Exam Questions with Correct
Solutions
1. Organic Chemistry correct answer: The branch of chemistry which deals with carbon
compounds, including those with no relationship to life.
2. Covalent Bond correct answer: Inter-atomic relationship created by the sharing of at least one
pair of electrons.
3. Saturated Hydrocarbon correct answer: Contain only only carbon-to-carbon single bonds. The
most chemically inert of
all organic compounds.
4. Unsaturated Hydrocarbon correct answer: Contain carbon-to-carbon double or triple
bonds.
5. Atomic Structure of Carbon correct answer: Atomic Number = 6, Protons = 6, Electrons = 6,
Atomic Weight = 12.0.
Electrons in first energy level = 2; second energy level = 4.
6. Carbon correct answer: An element that has the capacity to share four electrons in order to achieve a
more stable configuration.
7. Bonding correct answer: Carbon to Hydrogen or Halogens correct answer:
Shares one electron.
8. Bonding correct answer: Carbon to Oxygen or Sulfur correct answer: Shares up
to two electrons.
9. Bonding correct answer: Carbon to Nitrogen correct answer: Shares up to three
electrons
10. Halogens correct answer: Flourine (F), Chlorine (Cl), Bromine (Br), and Iodine (I).
11. Hydrocarbon Molecule correct answer: Contains only carbon and hydrogen. Can be
divided into aliphatic and aromatic
classes.
12. Substituted Hydrocarbon correct answer: One or more hydrogen atoms are replaced
by another atom or group of atoms called a Functional Group.
13. Aliphatic Hydrocarbon correct answer: A saturated hydrocarbon that contains only
hydrogen (the maximum number) and carbon. Does not contain benzene ring.
14. Aromatic Hydrocarbon correct answer: Contain at least one benzene ring or similar
structural features.

,Organic Chemistry Exam Questions with Correct
Solutions
15. Benzene correct answer: Consists of a ring of six carbon atoms with alternating single and
double carbon-carbon bonds.
16. Alkanes correct answer: (CnH2n+2)
17. Cycloalkanes correct answer: (CnH2n)
18. Classification correct answer: Primary correct answer: (1°) Carbons that are covalently
bonded to one other carbon. They are at the
end of a carbon chain and referred to as terminal carbons.
19. Classification correct answer: Secondary correct answer: (2°) Carbons that are
covalently bonded to two other carbons.
