chem 210 exam 3 with all questions correctly answered

less the more s character a carbocation has, the _____stable it is the same as when looking at an epoxide, the orientation around the oxygen is _________ the orientation around the double bond in the reactant BrOH when added with base makes an epoxide Br2 adds 2 Brs in anti conformation lindlar catalyst produces a Z alkene from an alkyne (adds 2 Hs in syn) add more electronegative atom, add pi bond 2 ways of producing an oxidation reaction remove electronegative atom, remove pi bond 2 ways of producing a reduction reaction HBr when this reaction occurs there is a scrambling of dashes and wedges (not just anti or syn, no fixed relationship) triple bond (base) reaction when the product has more carbons than the reactant, this reaction is needed radical halogenation when the reactant only has carbons and hydrogens, this reaction will occur first O3/Zn or OsO4/NMO/HIO4 when the product has less carbons than the reactant, one of these reaction is needed O3/Zn and OsO4/NMO/HIO4 these two reactions cleaves c-c bonds elimination when forming a double bond, this reaction is needed Li/NH3 creates an E alkene from an alkyne (adds 2 Hs anti) ozonolysis cuts through double bonds and adds oxygen to them less, more the lower the BDE for H-X, the ______ reactive X is, and the ______ selective X* is less, more in an X-OH reaction, the X bonds to the _____ substituted carbon and the OH bonds to the _____ substituted carbon H2 this reacts with triple and double bonds to form hydrocarbon chains in hydrogenation reactions carbon next to double bond allylic position is halogen, OH In a halohydrin reaction, the ___ is the electrophile and the ____ is the nucleophile anti a halohydrin reaction adds a halogen and an OH in ____ formation anti, water Oxymercuration is a ____ formation addition of ____ syn, water BH3 reaction is a ____ formation addition of _____ 2 Hs, syn, Pd in reduction of alkenes, ______ are added in ______ formation by attachment to ____ diasteriomers epoxides formed from mCPBA and BrOH are a pair of epoxide, water and H+ needed to create a trans diol epoxide, cat OsO4, NMO, water needed to create a cis diol gem-dibromide addition of HBr to a terminal alkyne gives a trans Br2 is added to an internal alkyne in a ______ formation methyl ketones oxymercuration of terminal alkynes gives mixture of little use oxymercuration of internal alkynes gives aldehydes hydroboration (BH3 reaction) of terminal alkynes gives tautomerization shift of atoms within a molecule enol alkene with alcohol attached is an aldehyde funtional group with O=C-H ketone functional group with C=O primary halide needed for acetylide alkylations markovnikov addition of water oxymercuration of alkenes is equivalent to less in alkene hydoboration (BH3) rxns the OH attaches to the ____ substituted caron hydrogens, double bonds catalytic hydrogenation adds ____ to remove _____ anti markovnikov addition alkene + HX= anti markovnikov with no stereochemical preference alkene + HBr = anti addition alkene + X2 = anti addition with OH- attached to more substituted carbon alkene + X2 + H20=
