Hydration of alkynes (via oxymercuration) gives good yields of single compounds only with symmetrical or terminal alkynes. Draw the major organic product(s) formed when hex-2-yne undergoes hydration in the presence of HgSO4 and H2SO4.
Please Solve these with step by step instructions with phases. It is very hard to understand how to solve them without a photograph and an explanation of why you chose each step
why is natural vanillin ethanolic extract considered to be of higher quality and therefore more expensive than the synthetic vanillin solution in ethanol
