Isoprene is a diene. How are the positions of double bonds located?

Text Solution

Verified by Experts

Isoprene is an unsatrurated hydrocarbon with molecular formula `C_(5)H_(8)`. One mole of isoprene on ozonolysis gives two moles of methanal and one mole of 2-oxopropanal. Hence is isoprene has two double bonds on terminal carbon atoms and a branch on one of the double bonded carbon atoms. Arranging the oxonolysis products in a sequence. we get,

Lemieux reagent consist of an aqueous solution of sodium periodate (NaIO_(4)) and a trace of KMnO_(4) It is used for locating the position of double bond in an alkene. During the reaction, the alkene is first oxidised to cis-diol which upon cleavage with sodium peroxide gives aldehydes and ketones (similar to ozonolysis). Hot solution of acidic or alkaline KMnO_(4) can also be used for locating double bond by observing the products which are ketones or carboxylic acids. Position of triple bond can be identified by similar process. An alkene on treatment with NaIO_(4) , KMnO_(4) "and" Na_(2)O_(2) gives acetone and acetaldehyde. The alkene is :
