Flourine is more electronegative than oxygen. Oxygen foms compound `Mn_2O_7` with menganese where Oxidation state of Mn is +7 but with fluorine, menganese forms `MnF_4` where oxidation state of Mn is +4 Explain.

Both O_2 and F_2 stabilize high oxidation states but the ability of oxygen to stabilize the higher oxidation state exceeds that of fluorine why?

Write formula of a compound where the transition metal is in +7 oxidation state.

Fluorine exhibits only+1 oxidation state, whereas other halogens also exhibit +1, +3, +5 and +7 oxidation states. Explain.

Account for the folloiwng: Mn^(2+) is more stable than Fe^(2+) towards oxidaton to +3 state.

Form compound statement ‘p and q' and state its truth value: (v) p : Zero is less than all positive integers q : Roots of X ^2 = 4 are real.

An organic compound A on treatment with ethanol yields a carboxylic acid B and a neutral compound C.On hydrolysis, C produces B and another compound D. D on oxidation produces B, which on heating with Ca (OH)_2 gives E (C_3H_6O) E form 2,4 Dinitrophenyl hydrazone derivatives but does not show Fehling test.
