Which of the following reaction is used to locate the position of double bond in the compound?

Explanation

OPTION A: Dehydration reactions can be defined as chemical reactions in which a water molecule is eliminated from the reactant molecule. OPTION B: Ozone (O3) is a highly reactive allotropic form of oxygen. It reacts vigorously with alkenes to form unstable molozonide. It rearranges spontaneously to form an ozonide. Ozonides are unstable compounds and are reduced directly by treatment with zinc and H2O. The reduction produces carbonyl compounds (aldehydes or ketones). Ozonolysis is used to locate the position of a double bond in an alkene. Hence, B is the correct option. OPTION C: Markonikov's rules state that when an asymmetric reagent is added to an asymmetric alkene, the positive part of the molecule attaches itself to that carbon atom involved in the double bond, holding a greater number of hydrogen atoms.OPTION D: It is an incorrect option.
