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.
