Question

$Mn{O}_4^{-}$ is of intense pink colour, through $Mn$ is in $(+7)$ oxidation state, it is due to

• A. Oxygen gives colour to it
• B. Charge transfer when $Mn(+7)$ gives its electron to oxygen and oxidise to $Mn(+8)$ temporarily
• C. Charge transfer when oxygen gives its electron to $Mn(+7)$ changing in $Mn(+6)$
• D. None is correct explanation

Answer 1

The correct option is C Charge transfer when oxygen gives its electron to $Mn(+7)$ changing in $Mn(+6)$

$Mn{O}_4^{-}$ involves charge transfer from oxygen to manganese. This results in intense purple coolur.
Manganese ion is reduced from -7 oxidation state to +6 oxidation state.
