The correct order of acidic character is:
(a)$\mathrm{Al}_{2} \mathrm{O}_{3}>\mathrm{MgO}>\mathrm{SiO}_{2}>\mathrm{P}_{4} \mathrm{O}_{10}$
(b)$\mathrm{P}_{4} \mathrm{O}_{10}>\mathrm{Al}_{2} \mathrm{O}_{3}>\mathrm{MgO}>\mathrm{SiO}_{2}$
(c)$\mathrm{P}_{4} \mathrm{O}_{10}>\mathrm{SiO}_{2}>\mathrm{Al}_{2} \mathrm{O}_{3}>\mathrm{MgO}$
(d)$\mathrm{SiO}_{2}>\mathrm{P}_{4} \mathrm{O}_{10}>\mathrm{Al}_{2} \mathrm{O}_{3}>\mathrm{MgO}$
Answer
Answer: C ✓ checked by 4AB · confidence high
Explanation
