Organic chemistry is the study of?
carbon compounds
which of the following is not a reason for the great number of carbon compounds?
carbon can exhibit many oxidation numbers
a saturated hydrocarbon is one that?
contains only carbon-carbon single bonds
which of the following formulas represents an alkane
c3h8
successive members of the alkane series differ from the preceding member by one additional
c atom and 2h atom
the members of the alkane series are similar in that each member has the same
general formula
isomers are compounds that have the same
number and kind of atoms in a molecule but different structures
the formula for nonacontane, a 90 carbon alkane is
C90H182
as the molecular mass of the members of the alkane series increases their boiling points?
increase
for which of the following hydrocarbon molecular formulas is there more than one possible structural formula?
C4H10
hydrocarbons that have rings of carbon atoms are called
cyclic hydrocarbons
a cyclic compound with 6 carbon atoms and 12 hydrocarbons is
cyclohexane
which of the following is an alkene
ethylene
an alkene has
a carbon-carbon double bond
the hydrocarbon family that feature molecules with a triple bound is

addition reaction occur in alkenes rather than in alkanes because alkenes have
double bonds

location of the functional group
which of the following compounds could be represented by the general formula ROH

which of the following alcohols have molecule with more than one hydroxyl group
glycerol
a formula that has a hydroxyl OH group attached to a benzene ring represents
phenol
an important use of phenol is
solvents

ester
when an alcohol reacts with the carboxylic acid the product formed is
ester
the amide functional group has a carbonyl group attached to
a N atom
a cyclic organic compound that contains at least one atom that is not a carbon atom is called
heterocyclic compound
a basic organic cyclic compound that contains at least one nitrogen atom and that occurs in many plants is called
alkaloid
a long chain protein molecule is an example of an
polymer
which is not a polymer
gluclose
the first semisynthetic polymer was actually made from a natural polymer which was
celluloid, based on cellulose from cotton
the first truly synthetic polymer was
bakelite made from phenol and formaldehyde
when addition polymers form, the monomer units are joined by
new bonds formed by electrons from the double bond
compared to LDPE, HDPE has a higher melting point because
has fewer branches in the chains allowing the molecules to pack more closely
