प्रश्न
Out of Cr3+ and Mn3+, which is a stronger oxidising agent and why?
Advertisements
उत्तर
Out of Cr3+ and Mn3+, Mn3+ is a stronger oxidising agent because it has 4 electrons in its valence shell and when it gains one electron to form Mn2+, it results in the half-filled (d5) configuration that has extra stability.
