1.	Isoprene is a diene. How are the positions of double bonds located?
Answer» Solution :The position of multiple bonds PRESENT between carbon atoms can be located by ozonolysis, Isoprene is an unsaturated 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 isoprene has two double bonds on terminal carbon atoms and a branch on one of the double BONDED carbon atoms. ARRANGING the ozonolysis products in a sequence, we GET, Hence isoprene is 2-methyl-1,3-butdiene.
