Which of the following reaction is metathesis reaction
Answers
Answer:
Methasis reaction
Methasis reactions are double displacement reactions i.e., the positive and negative ions present in the reactant appear to exchange partners. Option a shows a decomposition of KClO3, b shows diplacement of copper by zinc and c is an example of oxidation reduction reaction.
Metathesis reactions are chemical reactions in which two hydrocarbons (alkanes, alkenes or alkynes) are converted to two new hydrocarbons by the exchange of carbon–carbon single, double or triple bonds. These are usually catalyzed by a metal catalyst.
In metathesis reaction, the cations and anions exchange takes place between two ionic partners in solvent/medium (water). This is simply double-replacement reaction. All ions are surrounded by H2O molecules in hydrated form. A+ ion in water will be as [A(H2O)n]+ and X− as [X(H2O)n]−.
