CHEM 1020 PRACTICE FINAL EXAM 2026
COMPLETE QUESTIONS AND CORRECT
SOLUTIONS
◉ what is the reason why there are so many organic compounds?
Answer: carbon atoms can form stable covalent bonds with other
carbon atoms
◉ the vast number of organic compounds is due to the unique
chemistry of carbon. this chemistry involves Answer: formation of
long chains& isomerism
◉ Which applies to the manner in which carbon bonds in alkanes?
Answer: the bonds are formed with carbon using an sp3
configuration
◉ functional groups are Answer: to organic chem as polyatomic ions
are to inorganic chem, are chemically bound to each other in order
to develop larger molecules
◉ the alkanes represent one family of organic compounds Answer:
that is composed of carbon and hydrogen
,◉ formulas of organic compounds Answer: CH3CH2COOH,
CH3CH2OH,
CH3CH3CH3
◉ which is an alcohol Answer: CH3CH2OH
◉ what is meant by the term "saturated" when describing
hydrocarbons Answer: they are saturated with hydrogen and only
have single bonds between carbons
◉ correct statements on the naming of organic compounds Answer:
many compounds have been known long enough to have common
names, the naming system of organic compounds is set by IUPAC
rules, & the naming system requires that the longest carbon chain
must always be found
◉ cycloalkanes are Answer: NOT: compounds that have a flat
molecular structure,
saturated hydrocarbons, or compounds that cannot have hydrogens
removed and replaced by chlorine
◉ which of the following term applies to the alkanes Answer:
hydrophobic
, ◉ what is a characteristic shared by the alkanes Answer: flammable
◉ which of the following is a use for alkanes? Answer: a. fuel
b. lubricant
c. solvent
D. MORE THAN ONE IS CORRECT
◉ which of the following represent a saturated hyrdocarbon
Answer: C2H6
◉ All of the members of the alkane series of hydrocarbons have the
general formula __ Answer: CnH2n+2
◉ which of the following compounds can exhibit structural
isomerism? Answer: butane
◉ how many structural isomers are possible for compounds with a
molecular formula C4H10 Answer: 2
◉ which is a structural isomer of 2-methylbutane Answer: pentane
◉ how many structural isomers of C7H16 have 5 carbon atoms in
the longest carbon chain Answer: 5
