CHEM 1120 Exam 2 Review – Complete Chemistry Study Guide & Practice Test
(2026)
Hydrolysis - correct answer ✔✔A chemical process that splits a molecule by adding water.
dehydration reaction - correct answer ✔✔A chemical reaction in which two molecules become
covalently bonded to each other with the removal of a water molecule.
Oxidation - correct answer ✔✔loss of electrons
- addition of C-O bonds (at least for alcohols...)
reduction - correct answer ✔✔gain of electrons
- loss of C-O bonds (at least for alcohols...)
condensation reaction - correct answer ✔✔a chemical reaction in which two or more molecules
combine to produce water or another simple molecule
Lipids - correct answer ✔✔a class of compounds that are differentiated from other
biomolecules in a few ways
- NOT biopolymers
- NOT water soluble (and are made mostly of carbon)
fatty acid - correct answer ✔✔hydrocarbon chain often bonded to glycerol in a lipid
(nonpolar)
- unsaturated fatty acids in nature will almost always be cis-isomer
- in nature, have EVEN number carbons
