MCQ
Position of double bond in an organic compound is determined by
  • ✓
    Ozonolysis
  • B
    Oxidation
  • C
    Reduction
  • D
    Hydrogenation
✓

Answer

Correct option: A.
Ozonolysis
a
(a) Ozonolysis is useful in locating the position of a double bond in an alkene. The double bond is obtained by joining the carbon atoms of the two carbonyl compounds. For example

Let the product of ozonolysis be two molecules of ethanal.

$\mathop {C{H_3} - \mathop C\limits^{\mathop |\limits^H } = O}\limits_{} + O = \mathop C\limits^{\mathop |\limits^H } - C{H_3} \to $$\mathop {C{H_3} - CH = CH - C{H_3}}\limits_{{\rm{2}} - {\rm{Butene}}} $
