The correct order of acidic character of oxides in third period of per...
Explanation:
Acidic character of oxides:
- The acidic character of oxides generally increases from left to right across a period.
- This is because as we move from left to right, the electronegativity of the elements increases, leading to a stronger attraction for electrons and hence, a stronger acidic character in their oxides.
Third period of the periodic table:
- The third period of the periodic table consists of the elements sodium (Na) to argon (Ar).
- In this period, we have silicon (Si), phosphorus (P), sulfur (S), and chlorine (Cl) which form oxides.
Order of acidic character:
- SiO2: Silicon dioxide is an acidic oxide, but it is less acidic compared to the other oxides in the third period.
- P4O10: Phosphorus pentoxide is more acidic than SiO2 as phosphorus has a higher electronegativity.
- SO3: Sulfur trioxide is more acidic than P4O10 as sulfur has a higher electronegativity than phosphorus.
- Cl2O7: Dichlorine heptoxide is the most acidic oxide among the given options due to the high electronegativity of chlorine.
Therefore, the correct order of acidic character of oxides in the third period is SiO2 < p4o10="" />< so3="" />< cl2o7,="" which="" corresponds="" to="" option="" 'a'.="" cl2o7,="" which="" corresponds="" to="" option="" />
