Question

n2o4, no, n2o, n2o3, n2o5 ( arrange in increasing order of acidic strenth).​

Answer 1

Nitrous oxide (N2O) and nitric oxide (NO) are neutral. Dinitrogen trioxide (N2O3), nitrogen dioxide (NO2) and dinitrogen pentoxide (N2O5) are acidic. Acidic character increases with increase in oxidation number so the order is as follows:

N2O<NO<N2O3<NO2<N2O5.

The most acidic is N2O5 and the least acidic is N2O.

Answer 2

The compounds that are given are forms of Nitrogen.

Features of Nitrogen:

1. Nitrogen is a non-metallic element that belongs to Group 15 of the periodic table.
2. Nitrogen gas is colourless, odourless and tasteless in nature.
3. It forms part of all living organisms and is found in abundance in Earth's atmosphere.

The elements of Nitrogen:

1. $N^{2} O$ is Nitrous Oxide and is neutral.
2. $NO$ is Nitric Oxide and is neutral.
3. $N^{2} O_{3}$ is Dinitrogen Trioxide and is acidic.
4. $N^{2} O_{4}$ is Dinitrogen Tetroxide and is acidic.
5. $N^{2} O_{5}$ is Dinitrogen Pentoxide and is acidic.

Arranging in Increasing Order:

$N^{2} O$ < $NO$ < $N^{2} O_{3}$ < $N^{2} O_{4}$ < $N^{2} O_{5}$.

The most acidic is $N^{2} O_{5}$ and the least acidic is $N^{2} O$.
