need help on questions 3 and 4 please

Expt 6.2B, Hydration of Alkenes Fall Semester Name: 1. Draw your reaction (ChemSketch or ChemDraw). It should fit on one line and look good. Show all products actually formed + H₂O H₂SO4 norbornene exo- norborneol 2. What was the stereochemistry (endo or exo) of your reaction? How do you know? exo 3. The carbocation in our particular reaction was secondary. Was a rearrangement possible? If so, why didn't it occur? 4. Oxymercuration-demercuration is often used as a method to give Markovnikov addition of water and alcohols to alkenes. What is a major advantage (in general) of the oxymercuration-demercuration method compared to aqueous sulfuric acid? Would the oxymercuration-demercuration method have helped in our particular reaction? Why or why not?

Answer 1

HA 22504 + H2O 그애 morborene exo-product duchy Although the hydration of nor produces both the p 3 nyaration of norborene all exo-product as well as endo-product The carbocation formed given is secondary z o rearrangeut is not possible because it ne rearraufement was done then the calbo-cation Janed will be a which is higuly unstable due to its large energy . mo oxy mercuration - demercuration us dten wed as a method to give Markonikoff's aaddition of water and alcohols to alcaue no doubto but the ony mercuration - demercuratio is an electrophilic addition reaction that neach wiris Ac-o-rg-One (mercuric acetate) to yield alconals but note here, that carbo-cations are not formed in this process and thus rearrangements are not possible Hence could be med in particular reaction Advantage of using this method is in na otucate acids like aquedus to soq some alkenes remains insoluble this producing side product ui while oxymer curation - demercuration are not generally observed ... side products
