Question

The order in which the following oxides are arranged according to decreasing basic nature is ​

Answer 1

Explanation:

C u O , N a 2 O , M g O , A l 2 O 3 CuO,Na_2O,MgO,Al_2O_3 CuO,Na2O,MgO,Al2O3.

Answer 2

Answer:

the answer is Na2O,MgO,Al2O3,CuO

cuo is a non metal oxide with low basic nature it should be last

coming to na2o,mgo,al2o3

consider the  metals in them

na,mg,al

they belongs to same period

through a period left to right basic nature decreases

hence,na2o>mgo>al2o3>cuo

hence proved! hope it helps......
