Alkaline potassium permanganate (KMnO 4 ) can be used to bring about the addition of two OH

Question:

Alkaline potassium permanganate (KMnO₄) can be used to bring about the addition of two ¬OH groups to an alkene double bond. This reaction has been shown in several cases to be a stereospecific syn-addition. Given the stereochemistry of the product shown in Fig. P7.53, what stereoisomer of alkene A was used in the reaction? Explain. CH3(CH),CH=CH(CH), A Figure P7.53 CH3 KMnO4/OH OH OH IT CH3(CH)7CH-CH(CH),CH3 meso stereoisomer
