CHEM 1020 FINAL EXAMwhat is a major difference between organic and inorganic compounds? - ANS-organic
contain carbon
what is the reason why there are so many organic compounds? - ANS-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 - ANS-formation of long chains& isomerism
Which applies to the manner in which carbon bonds in alkanes? - ANS-the bonds are
formed with carbon using an sp3 configuration
functional groups are - ANS-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 - ANS-that is composed of
carbon and hydrogen
formulas of organic compounds - ANS-CH3CH2COOH, CH3CH2OH,
CH3CH3CH3
which is an alcohol - ANS-CH3CH2OH
what is meant by the term "saturated" when describing hydrocarbons - ANS-they are
saturated with hydrogen and only have single bonds between carbons
correct statements on the naming of organic compounds - ANS-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 - ANS-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 - ANS-hydrophobic
, what is a characteristic shared by the alkanes - ANS-flammable
which of the following is a use for alkanes? - ANS-a. fuel
b. lubricant
c. solvent
D. MORE THAN ONE IS CORRECT
which of the following represent a saturated hyrdocarbon - ANS-C2H6
All of the members of the alkane series of hydrocarbons have the general formula __ -
ANS-CnH2n+2
which of the following compounds can exhibit structural isomerism? - ANS-butane
how many structural isomers are possible for compounds with a molecular formula
C4H10 - ANS-2
which is a structural isomer of 2-methylbutane - ANS-pentane
how many structural isomers of C7H16 have 5 carbon atoms in the longest carbon
chain - ANS-5
A compound is incorrectly named 2-ethyl 1-2,4 - dimethylhexane. What would be the
correct IUPAC name - ANS-3,3,5-trimethylheptane
A general formula for cycloalkanes is - ANS-CnH2n
which of the following cycloalkanes contains a total of 12 carbon atoms -
ANS-1-ethyl-2methylcyclononane
how many isomers (structural and geometric) exist for dibromocyclopentane (C5H8Br2)
- ANS-5
how many isomers exist for dichlorocyclopropane (C3H4Cl2) - ANS-3
an alkane with 10 carbon atoms is a __ @ room temp - ANS-liquid
Alkanes are ___ in water and ___ than water - ANS-insoluble, less dense
complete combustion of pentane produces - ANS-CO2 & H2O
