- Which of the following is/are the expected product/s of the reaction of 2-pentanone (CH3COCH2CH2CH3) with excess Br2, followed by OH-? CHBr3 + CH3CH2CH2COOH BrCH2COCH2CH2CH3 CHBr3 + CH3CH2CH2COO- CH3COCHBrCH2CH3There are two isomeric cyclohexa-1,4-diene products when benzoic acid undergoes the Birch reduction (see Problem 25.24). (a) Draw the mechanism that leads tothe formation of the major product. (b) Will the Birchreduction of benzoic acid occur faster or slower than theBirch reduction of benzene itself? Hint: Is –CO2H anelectron-donating or an electron-withdrawing group?An inexperienced graduate student treated dec-5-ene with borane in THF, placed the flask in a refrigerator, and left for aparty. When he returned from the party, he discovered that the refrigerator was broken and that it had gotten quite warminside. Although all the THF had evaporated from the flask, he treated the residue with basic hydrogen peroxide. Tohis surprise, he recovered a fair yield of decan-1-ol. Use a mechanism to show how this reaction might have occurred.(Hint: The addition of BH3 is reversible.)*8
