Oxidation of alcohols by strong oxidants in acid medium

Exercise 2

    

1) The menthol molecule is : Menthol is used to make menthone, used in perfumes, menthol cigarettes and drinks. Draw the redox system which reflects the oxidation with permanganate under acidic conditions. 2) Calculate the mass of menthol that can be oxidized by a solution of $0.160\;g$ permanganate in $40\;mL$ of water.

1) 2) $n_{KMnO_4}$ $=$ $\frac{0.160}{158}$ $=$ $0.001012$ $n_{C_{10}H_{20}O}$ $=$ $0.001012\frac{5}{2}$ $=$ $0.00253$ $m_{C_{10}H_{20}O}$ $=$ $0.00253\cdot 156$ $=$ $0.395\;g$
