9-PAY ATTENTION TO THE ARROWS FOR TAUTOMERIZATION REACTIONS. DOUBLE CHECK WITH THE POWERPOINT OR THE BOOK FOR ANY DISCREPANCIES !!!!!!!!a)
b) Both A and B products are obtained but the mechanism shown is meant to obtain product B
10- Product C
Product F
The carbon connected to the OH has two hydrogen atoms that show a signal of a singlet in 3-4 ppm region
Product G
The carbon connected to OH shows no signals because it has no hydrogens
Product K
The carbon connected to the OH has one hydrogen atom that shows a doublet in the 3-4ppm region because its neighboring carbon has a hydrogen atom that splits the signal.
