2026/2027
Organic Chemistry - ANS The branch of chemistry which deals with carbon compounds,
including those with no relationship to life.
Covalent Bond - ANS Inter-atomic relationship created by the sharing of at least one pair of
electrons.
Saturated Hydrocarbon - ANS Contain only only carbon-to-carbon single bonds. The most
chemically inert of all organic compounds.
Unsaturated Hydrocarbon - ANS Contain carbon-to-carbon double or triple bonds.
Atomic Structure of Carbon - ANS Atomic Number = 6, Protons = 6, Electrons = 6, Atomic
Weight = 12.0. Electrons in first energy level = 2; second energy level = 4.
Carbon - ANS An element that has the capacity to share four electrons in order to achieve a
more stable configuration.
Bonding: Carbon to Hydrogen or Halogens - ANS Shares one electron.

, Bonding: Carbon to Oxygen or Sulfur - ANS Shares up to two electrons.
Bonding: Carbon to Nitrogen - ANS Shares up to three electrons
Halogens - ANS Flourine (F), Chlorine (Cl), Bromine (Br), and Iodine (I).
Hydrocarbon Molecule - ANS Contains only carbon and hydrogen. Can be divided into
aliphatic and aromatic classes.
Substituted Hydrocarbon - ANS One or more hydrogen atoms are replaced by another atom
or group of atoms called a Functional Group.
Aliphatic Hydrocarbon - ANS A saturated hydrocarbon that contains only hydrogen (the
maximum number) and carbon. Does not contain benzene ring.
Aromatic Hydrocarbon - ANS Contain at least one benzene ring or similar structural features.
Benzene - ANS Consists of a ring of six carbon atoms with alternating single and double
carbon-carbon bonds.
Alkanes - ANS (CnH2n+2)
Cycloalkanes - ANS (CnH2n)
Classification: Primary - ANS (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.
