1.	Which one of the following orders presents the correct sequence of the increasing basic nature of the given oxides?A. `Al_(2)O_(3)ltMgOltNa_(2)OltK_(2)O`B. `MgOltK_(2)OltAl_(2)O_(3)ltNa_(2)O`C. `Na_(2)OltK_(2)OltMgOltAl_(2)O_(3)`D. `K_(2)OltNa_(2)OltAl_(2)O_(3)ltMgO`
Answer» Correct Answer - A As metallic character of element attched to oxygen atom increases, the difference between the electronegativity values of element and oxygen increases and thus basic character of oxides increases and vice-versa. Hence the increasing correct order of basic nature `Al_(2)O_(3)ltMgOltNa_(2)OltK_(2)O`.
