Which of the following sequence correctly represents the decreasing acidic nature of oxides?

Which of the following sequence correctly represents the decreasing acidic nature of oxides?
  1. $\mathrm{Li}_{2} \mathrm{O}>\mathrm{BeO}>\mathrm{B}_{2} \mathrm{O}_{3}>\mathrm{CO}_{2}>\mathrm{N}_{2} \mathrm{O}_{3}$
  2. $\mathrm{N}_{2} \mathrm{O}_{3}>\mathrm{CO}_{2}>\mathrm{B}_{2} \mathrm{O}_{3}>\mathrm{BeO}>\mathrm{Li}_{2} \mathrm{O}$
  3. $\mathrm{CO}_{2}>\mathrm{N}_{2} \mathrm{O}_{3}>\mathrm{B}_{2} \mathrm{O}_{3}>\mathrm{BeO}>\mathrm{Li}_{2} \mathrm{O}$
  4. $\mathrm{B}_{2} \mathrm{O}_{3}>\mathrm{CO}_{2}>\mathrm{N}_{2} \mathrm{O}_{3}>\mathrm{Li}_{2} \mathrm{O}>\mathrm{BeO}$

Solution

On passing from left to right in a period, acidic character of the normal oxides of the elements increases with increase in electronegativity.
