SOLUTION
⩥ the same as. Answer: when looking at an epoxide, the orientation
around the oxygen is _________ the orientation around the double bond
in the reactant
⩥ BrOH. Answer: when added with base makes an epoxide
⩥ Br2. Answer: adds 2 Brs in anti conformation
⩥ lindlar catalyst. Answer: produces a Z alkene from an alkyne (adds 2
Hs in syn)
⩥ add more electronegative atom, add pi bond. Answer: 2 ways of
producing an oxidation reaction
⩥ remove electronegative atom, remove pi bond. Answer: 2 ways of
producing a reduction reaction
⩥ HBr. Answer: when this reaction occurs there is a scrambling of
dashes and wedges (not just anti or syn, no fixed relationship)
, ⩥ triple bond (base) reaction. Answer: when the product has more
carbons than the reactant, this reaction is needed
⩥ radical halogenation. Answer: when the reactant only has carbons and
hydrogens, this reaction will occur first
⩥ O3/Zn or OsO4/NMO/HIO4. Answer: when the product has less
carbons than the reactant, one of these reaction is needed
⩥ O3/Zn and OsO4/NMO/HIO4. Answer: these two reactions cleaves c-
c bonds
⩥ elimination. Answer: when forming a double bond, this reaction is
needed
⩥ Li/NH3. Answer: creates an E alkene from an alkyne (adds 2 Hs anti)
⩥ ozonolysis. Answer: cuts through double bonds and adds oxygen to
them
⩥ less, more. Answer: the lower the BDE for H-X*, the ______ reactive
X* is, and the ______ selective X* is
