Any proper mechanism of hydroboration- oxidation must explain the observed____[ex anti] addition of the H and OH to the alkene as well as the____ [ex mixed markovnikov] regiochemistry
One possible way of determining the identity of an alkene, is to let itundergo an oxidative cleavage reaction in the presence of hot basicpotassium permanganate. You are given two containers said to containdifferent alkenes. Container A is marked as cis / trans‐2‐butene andcontainer B as 2‐methyl‐1‐butene. Explain by referring to the formation ofproducts, how you would verify the identity of the alkenes.
Can someone explain the answers to 28, 29, and 30? The answers are B, A, A. I understand lindar catalyst makes cis alkenes and Na/NH3 makes trans alkenes but I dont understand how the second step of Br2, OsO4 influences the stereochemistry between the 2 . Will rate quickly if helpful. Thanks!
