MCQ
The order in which the following oxides are arranged according to decreasing basic nature is
- ✓$N{a_2}O,\,MgO,\,A{l_2}{O_3},\,CuO$
- B$MgO,\,A{l_2}{O_3},\,CuO,\,N{a_2}O$
- C$A{l_2}{O_3},\,MgO,\,CuO,\,N{a_2}O$
- D$CuO,\,N{a_2}O,\,MgO,\,A{l_2}{O_3}$
✓
Answer
Correct option: A.
$N{a_2}O,\,MgO,\,A{l_2}{O_3},\,CuO$
a
(a) $N{a_2}O,\,\,MgO,\,\,A{l_2}{O_3},\,\,CuO$. More the metallic character higher the ${e^ - }$ donating tendency.
(a) $N{a_2}O,\,\,MgO,\,\,A{l_2}{O_3},\,\,CuO$. More the metallic character higher the ${e^ - }$ donating tendency.
Therefore lower the $I.E.$ more the basic nature of oxide.
