Transition metals vary widely in their chemical reactivity. Many of them are sufficiently electropositive to dissolve in mineral acids, although a few are noble i.e., they are unaffected by single acids. These elements form various type of halides and oxides. The ability of fluorine to stabilise the highest oxidation state is due to either higher lattice energy or due to higher bond enthalpy. The highest oxidation number in the oxides coincides with the group number and is attained in Sc2O3 to Mn2O7.Q. Which among the following oxides of chromium is of highest acidic strength?
प्रश्न - निम्नलिखित में से क्रोमियम के कौनसे ऑक्साइड की अम्लीय सामर्थ्य अधिकतम है?
