$CrO_3$

Vedclass · Answer

(A) In the $d$-block elements,the stability of the higher oxidation state increases down the group. $Cr$ is in the $3d$ series,$Mo$ is in the $4d$ series,and $W$ is in the $5d$ series. As we move down the group,the stability of the $+6$ oxidation state increases,meaning the tendency to get reduced decreases. Therefore,the oxidizing power decreases as we go down the group: $CrO_3 > MoO_3 > WO_3$. Thus,$CrO_3$ acts as the best oxidizing agent among the given options.
