EEE 380 Exam 1 Questions and Correct
Answers/ Latest Update / Already Graded
organic compounds
Ans: most common elements, at least one carbon bond, longer
chain of carbons = higher boiling point, larger compound =
more potential for more isomers
hydrocarbons: alkanes
Ans: saturated (no double bonds)
ex: methane, ethane, propane, butane
hydrocarbons: alkenes
Ans: unsaturated (has double bonds)
hydrocarbons: alkynes
Ans: unsaturated (triple bonds)
BOD
Ans: biochemical oxygen demand - high BOD = needs lots of
O2 to fully metabolize

halogenated hydrocarbons
Ans: replaces C-H with C-X bond (X is Cl, Br, F, I)
high GWP, even for 100 years
low boiling point - high pressurized liquids or gases
ex: refrigerants, disinfection by products
electronegativity
Ans: function of atomic radius and net charge
smaller radius/ higher net charge = greater EN
alcohols
Ans: OH attached to terminal carbon
shorter chain are very soluble
useful as a co-solvent - helps dissolve other OCs in water
can be mobile if released into groundwater
secondary alcohols
Ans: OH attached to carbon that is attached to 2 other carbon
atoms

negative average oxidation state
Ans: atom has more room to react
aldehydes
Ans: have central C atom double bonded to O_2, a single bond
to hydrogen, and third substituent
common solvents + reaction intermediates
ketones
Ans: C=O (carbonyl group), at least one hydroxyl group bound
to saturated carbon
R and R' can be a variety of carbon containing substituents
common solvents + reaction intermediates + biological
production called ketosis
carboxylic acids
Ans: organic acid that contains a carboxyl group attached to an
R group
shorter chain = very soluble
some are volatile
