1B. 2-methyl-2-butanol reacts with ___ to form 2-methyl-2-butene.
H2SO4
NaOH
NaOC2H5
1C. 2-bromopentane reacts with NaOC2H5 to form three products. The major product is:
1-pentene
cis-2-pentene
trans-2-pentene
1D. 2-bromo-2-methylbutane reacts with NaOH. Possible products are: a. 2-methyl-2-butene, b. 3-methyl-1-butene, c. 3-methyl-2-butanol, d. 2-methyl-2-butanol. The substitution product is ____. The elimination product is _____.
c/a
c/b
d/a
d/b
1E. When 2-bromo-2-methylbutane reacts with NaOH, the major product is the ____ product. If you want the major product to be the ____ product, you could use ____ instead of NaOH.
elimination/substitution/H2O
substitution/elimination/NaOC2H5
elimination/substitution/ NaOC2H5
Explanation / Answer
1A Beta.
1B H2SO4
1C. trans-2-pentene
1D. The substitution product is2-methyl-2-butene
The elimination product is 2-methyl-2-butanol.
1E. When 2-bromo-2-methylbutane reacts with NaOH, the major product is the substitution product. If you want the major product to be the elimination product, you could use NaOC2H5 instead of NaOH.
