Question

mn2+ compound more stable than fe2+ towards oxidation to their +3 state

Answer 1

electronic configuration of $Mn^{+2}$=$[AR]^{18}3d^{5}$and electronic configuration of[tex]Fe^{ +2} [/tex]  =$[AR]^{18}3d^{6} </span> since full and half filled orbitals r more stable then [tex] Mn^{+2}$ is more stable then$Fe^{ +2}$  because it  has half filled orbitalad since$Fe^{ +2}$ releases 1 more electron it also gets stable.
