$MoO_3$

Vedclass · Answer

(B) $1$. An oxidising agent is a substance that undergoes reduction by gaining electrons.$2$. In $CrO_3$, $CrO_4^{2-}$, and $Cr_2O_7^{2-}$, chromium is in the $+6$ oxidation state, which is a common state for chromium to be reduced to lower oxidation states.$3$. In $MoO_3$, molybdenum is in the $+6$ oxidation state. Due to the stability of the $+6$ oxidation state in group $6$ elements, $Mo(VI)$ is much more stable than $Cr(VI)$.$4$. Therefore, $MoO_3$ does not readily undergo reduction and acts as a very poor oxidising agent compared to the chromium species.
