Vedclass · Answer

(D) In the periodic table,the acidic nature of oxides increases from left to right across a period,while the basic character increases from top to bottom down a group.$SeO_2$ is an acidic oxide (non-metal oxide).$Al_2O_3$ is an amphoteric oxide.$Sb_2O_3$ is amphoteric (with more basic character than $Al_2O_3$ due to its position in the group).$Bi_2O_3$ is the most basic oxide among the given options because $Bi$ is the most metallic element in the group.Therefore,the order of basic nature is $Bi_2O_3 > Sb_2O_3 > Al_2O_3 > SeO_2$.
