The different steps involved in Victor Meyer methods are as below

  1. The alcohol is treated with iodine in presence of red phosphorous to obtain iodol alkane.
  2. Iodoalkane so formed is allow to react with alcoholic silver nitrate in order to obtained nitroalkane.
  3. The nitroalkane is treated with nitrous acid ( the mixture of Nano2 +HCl) and the resulting solution is made alkaline.
