Q. The strength of the oxyacids decreases in the following order

1. $HN{O}_3>H_{3}P{O}_4>H_{3}As{O}_4>H_{3}Sb{O}_4$
2. $HN{O}_3>H_{3}P{O}_4>H_{3}Sb{O}_4>H_{3}As{O}_4$
3. $HN{O}_3>H_{3}P{O}_4=H_{3}As{O}_4>H_{3}Sb{O}_4$
4. $HN{O}_3>H_{3}P{O}_4>H_{3}As{O}_4=H_{3}Sb{O}_4$

Q. Among the following oxides, the correct order of acidity is:

1. $N_2{O}_5$ > $N{O}_2$> $N_2{O}_3$ > $N_{2}O$
2. $N_{2}O$ > $N_2{O}_3$ > $N_2{O}_5$ > $N{O}_2$
3. $N_2{O}_5$ < $N{O}_2$ < $N_2{O}_3$ < $N_{2}O$
4. $N_2{O}_5$ > $N{O}_2$ > $N_{2}O$ >$N_2{O}_3$
