Options

  1. ATo dissolve argentite ore which of the following is used?
  2. BTo dissolve argentite ore which of the following is used?
  3. CTo dissolve argentite ore which of the following is used?
  4. DTo dissolve argentite ore which of the following is used?

Correct answer

A. To dissolve argentite ore which of the following is used?

Step-by-step solution

Stability of alkene ∝1 Heat of hydrogenation of alkene \propto \frac{1}{\text{ Heat of hydrogenation of alkene }} Greater the number of alkyl groups attached to the doubly bonded carbon atoms, more stable is the alkene. Hence, given alkene follow the following order of stability. Hence, faster hydrogenation in
