CHEM 219 PRINCIPLES OF ORGANIC
CHEMISTRY MODULE 6 COMPREHENSIVE
EXAM 2026
◉ Inorganic chemistry. Answer: The study of compounds that do not
contain carbon or focus on non-carbon atoms.
◉ Hydrocarbons. Answer: The simplest types of organic compounds,
containing only carbons and hydrogens.
◉ Heteroatoms. Answer: Atoms other than carbon or hydrogen
found in biological organic compounds.
◉ Alkanes. Answer: Hydrocarbons containing only single bonds
between carbons; also called saturated hydrocarbons.
◉ Saturated hydrocarbons. Answer: Hydrocarbons that contain only
single bonds between carbon atoms.
◉ Alkenes. Answer: Hydrocarbons with double bonds between
carbons; also called unsaturated hydrocarbons.
,◉ Unsaturated hydrocarbons. Answer: Hydrocarbons that contain
one or more double bonds between carbon atoms.
◉ Expanded structures. Answer: Representations of organic
compounds showing every atom and bond, including bonding
electrons.
◉ 3-D ball and stick models. Answer: A method to represent organic
compounds that provides a clearer spatial understanding.
◉ Skeletal line drawings. Answer: 2-D representations of organic
compounds where carbon and hydrogen atoms are implied.
◉ Condensed structure. Answer: A representation of organic
compounds where atoms are shown but not the bonds, e.g.,
CH3CH2CH2CH3.
◉ Lewis structure. Answer: A representation of molecules
emphasizing that bonds are pairs of electrons.
◉ Bonding requirement. Answer: Each carbon atom has exactly 4
covalent bonds, while every hydrogen has 1 bond.
, ◉ Double bonds. Answer: Bonds formed between carbons where 2
pairs of electrons are shared.
◉ Triple bonds. Answer: Bonds formed between carbons where 3
pairs of electrons are shared; often ignored in basic studies.
◉ Like-dissolves-like rule. Answer: A principle stating that polar
solvents dissolve polar solutes, and nonpolar solvents dissolve
nonpolar solutes.
◉ Biological organic compounds. Answer: Organic compounds that
contain atoms other than carbon and hydrogen.
◉ Carbon chains. Answer: Long chains formed by carbon atoms,
which may be branched.
◉ Hydrocarbon components. Answer: The parts of organic
compounds that are dominated by hydrocarbons, such as in fats
(lipids).
◉ Bond types in hydrocarbons. Answer: Hydrocarbons can have
single, double, or triple bonds between carbon atoms.
