Which of the following statements is true regarding the base hydrolysis of the coordination complex [Co(py)4Cl2]+ (where py = pyridine)?
Verified Solution4 OptionsUpdated: October 2026👁️1 View
Share:
- 1The reaction involves a seven-coordinate stable intermediate of the form [Co(py)4Cl2(OH)]
- 2The reaction proceeds efficiently via a typical SN1CB mechanism involving a conjugate base
- 3The reaction rate does not depend on the hydroxide ion concentration because pyridine lacks acidic protons required for the SN1CB mechanism✓
- 4The rate expression is given by Rate = k[Co(py)4Cl2]+[OH-]
Correct answer
The reaction rate does not depend on the hydroxide ion concentration because pyridine lacks acidic protons required for the SN1CB mechanism
