Question
Please fill the blank and answer all of them
1-An oxidation results in the _______________________ of the number of C—Z bonds (by the way, what does Z include?) and a ___________________ results in the increase of the number of ______________ bonds.
2-• List the three types of reducing agents. What species are all three delivering to the starting material?
3• The reduction of an alkene yields an ______________________. The reduction of an alkyne also yields an __________________ unless Lindlar’s catalyst is used. Then a (be specific about stereochem) __________________________ is the result. If Na/NH3 is used, a (be specific about stereochem) __________________________ is the result.
4• Before hydrogenation, a compound had the molecular formula of C7H10. After hydrogenation, the compound had a molecular formula of C7H14. How many rings and how many bonds were in the original molecule?
Explanation / Answer
(1) decrease, C-Z where Z = H)
(2) Reducing agents, LiAlH4 H- (hydrode)
NaBH4 H- (hydride)
H2/Pd, H
(3) Alkane, alkane
alkyne gives cis alkene in the present of lindlar's catlyst and trans alkene in the presence of Na/NH3
(4)
Molecular formual os saturated hydro carbon is CnH2n+2 where n = number of carbons.
forn n = 7, C7H16
We have C7H14,
Since 4 hydrogens are added, there must be two pi bonds and one ring(which balances the remainig)
