Question

Among :

$a\left)N{a}_{2}Ob\right)MgOc\left)A{l}_2{O}_{3}d\right)P_2{O}_{5}e)C{l}_2{O}_7$

the most basic, most acidic and amphoteric oxide can be ________.

• A. a,b,c
• B. b,e,c
• C. a,e,c
• D. e,c,a

Answer 1

The correct option is C a,e,c

Metal being electropositive in nature form basic oxide .non metals being electronegative in nature from acidic oxides .

so the extent of acidity and basicity in oxide depends on electropositive and electronegative nature of elements.

most basic oxide: $N{a}_{2}O$

most acidic oxide $C{l}_2{O}_7$

amphoteric oxide: $A{l}_2{O}_3$
