Question

q1: draw the reaction of cyclohexane with PBP and with KMno4. be careful about stereochemistry ?

q2:why would someone use PBP instead of Br2?

q3: draw the structure of (+)-x-pinene and (-)-x-pinene and assign R/S to each chiral center.

q4: your test tubes shouldnbe alcohol free for the kMnO4 test why?

Ans © KM nou will act as a oxidizing Reagent For Alcohol specially I and 2 -0H, Hence It will give oxidation Type side Reaction with Alcohol during Kinou-Test also called Baeyer's ensaturation Tert. KMnOy R CH-OH R CHO] . Primary Toveroxidation love Alcohol . R coon KMnoy R - on Roo Alcohol) noy U kwam Both kmalu perete Both KMnOy Test as well as Alcohol oxidation will occur

Answer (1) Deas Student, PBP and KMnOm does react with Compounds having double bond and touhle bond, Means Sithesi alkone and alkyne will give positive test with PBP and KMNO4 · Hence Cydohexane and PBP. KMnO4 NOB913 Cyclohexane Potassium per magnet BA Pyudinium bromida pez bromide (PBP) PBP 'No geachion will occur 0=0 KMnOn NOTE? If Cyclohexene ús present PBP on By Anbi addition of Bromine KMnO4 Syn Dihydroxylation
