The 1H-NMR spectrum for
Compound A is shown below. Compound A reacts with borane in
tetrahydrofuran followed by oxidation with hydrogen peroxide in
sodium hydroxide to form Compound B. Select the correct IUPAC names
for Compounds A and B from the list below.
Homework Answers
A - option A
B- option F
Since the reaction is an example for hydroboration oxidation by Anti-markonikoff rule hence less substitited alcohol is the major.
Signal at far down field 5.25 ppm is due to olefinic Hydrogens.
