CHEM 1020 FINAL EXAM| 184 QUESTIONS|
WITH COMPLETE SOLUTIONS
what is a major difference between organic and inorganic compounds? - ANSWER-
organic contain carbon
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
A compound is incorrectly named 2-ethyl 1-2,4 - dimethylhexane. What would be
the correct IUPAC name - ANSWER-3,3,5-trimethylheptane
A general formula for cycloalkanes is - ANSWER-CnH2n
which of the following cycloalkanes contains a total of 12 carbon atoms -
ANSWER-1-ethyl-2methylcyclononane
how many isomers (structural and geometric) exist for dibromocyclopentane
(C5H8Br2) - ANSWER-5
