CHEM 1020 FINAL EXAM QUESTIONS
WITH 100% CORRECT ANSWERS
2025/2026 VERSION.
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

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
