Alkenes and Alkynes

QuestionAnswer
hydrocarbons that contain a carbon-carbon double bond Alkenes
hydrocarbons that contain a carbon-carbon triple bond Alkynes
alkenes and alkynes are this unsaturated
when two double bonds are present in a compounds alkadienes
double bonds that are right next to one another Cumulated
multiple bonds that alternate with single bonds conjugated
more than one single bond between multiple bonds nonconjugated
rules for naming alkenes and alkynes IUPAC rules
these orbitals lie in a plane and are directed to the corners of an equilateral triangle sp3- hybridized orbitals
the bond formed by lateral p-orbital overlap pi bond
the most common reaction addition
alkenes and reagents are this when only one addition product is possible symmetric
akenes and regents are this when two products are possible unsymmetric
a reaction that gives only one of the two possible regoisomers regiospecific
a reaction that gives mainly one product regioselective
when a unsymmetric reagent adds to an unymmetric alkene, the electropositive part of the reagent bonds to the carbon of the double bond that has the greater number of hydrogen atoms attached to it Markovnikov's rule
electron-poor reagents; seek electrons; positive ions electrophiles
electron rich; form bonds by donating electrons to an electrophile nucleophiles
a positively charged carbon atom bonded to three other atoms carbocation
when the first step in the additions is attack by the electrophile the whole process is what? electrophile addition reaction
is this when three R groups are atatched tertiary
is this when two R groups are attached secondary
is this when one R group is attatched primary

a reaction that gives off heat energy exothermic
a reaction that takes in heat energy endothermic
heat energy enthalpy; H
shows the changes in energy that occur in the course of a reaction reaction energy diagram
a structure with maximum energy for a particular reaction step transition state
the difference in energy between reactants and the transitions state activiation energy
activation determines this reaction rate
two factors that affect reaction rates temperature and catalysts
the addition of hydrogen to alkenes in the presence of a catalyst hydrogenation
a large molecule containing a repeating unit derived from small molecules polymer
the process of polymer formation polymerization
