Options
- ALi 2 O > BeO > CO 2 > B 2 O 3 > N 2 O 3
- BCO 2 > N 2 O 3 > B 2 O 3 > Li 2 O > BeO
- CCO 2 > BeO > Li 2 O > B 2 O 3 > N 2 O 3
- DN 2 O 3 > CO 2 > B 2 O 3 > BeO > Li 2 O
Correct answer
D. N 2 O 3 > CO 2 > B 2 O 3 > BeO > Li 2 O
Step-by-step solution
A binary compound of oxygen with another element is called oxide Oxides can be simple (e.g., MgO, Al 2 O 3 ) or mixed (Pb 3 O 4 ,Fe 3 O 4 ). Simple oxides can be classified on the basis of their acidic, basic or amphoteric character. An oxide that combines with water to give an acid is termed acidic oxide (e.g., SO 2 ,Cl 2 O 7 ,CO 2 , N 2 O 5 ). For example, SO 2 combines with water to give H 2 SO 3 , an acid. The oxides which give a base with water are known as basic oxides (e.g., Na 2 O, CaO, BaO). For example, C
