Question

The correct order of acidic strength of oxides of nitrogen is :

• A. $NO$<$N{O}_2$<$N_{2}O$<$N_2{O}_3$<$N_2$$O_5$
• B. $N_{2}O$<$NO$<$N_2$$O_3$<$N_2{O}_4$<$N_2{O}_5$
• C. $NO$<$N_{2}O$<$N_2{O}_3$<$N_2$$O_5$<$N_2$$O_4$
• D. $NO$<$N_{2}O$<$N_2{O}_5$<$N_2{O}_3$<$N_2{O}_4$

Answer 1

The correct option is B $N_{2}O$<$NO$<$N_2$$O_3$<$N_2{O}_4$<$N_2{O}_5$

The acidic nature increase while oxidising nature decreases with increase of oxidation state of nitrogen.
$N_{2}O$<$NO$<$N_2$$O_3$<$N_2{O}_4$<$N_2{O}_5$
+1 +2 +3 +4 +5
