Select correct statement about N2O4.a)It self ionises as NO+, NO3b)N2O...
N2O4 is a chemical compound known as dinitrogen tetroxide. Let's analyze each option to determine the correct statement about N2O4:

a) It self-ionizes as NO, NO3
N2O4 does not self-ionize into NO and NO3. Self-ionization occurs when a compound dissociates into ions in the absence of any external source of ions. In the case of N2O4, it does not dissociate into NO and NO3 ions. Therefore, this statement is incorrect.

b) N2O4 is paramagnetic
Paramagnetism refers to the property of a substance to be attracted by a magnetic field due to the presence of unpaired electrons. In the case of N2O4, it has a dimeric structure, meaning it consists of two N2O2 units. Each N2O2 unit has two unpaired electrons, making a total of four unpaired electrons in N2O4. This presence of unpaired electrons makes N2O4 paramagnetic. Therefore, this statement is correct.

c) Substance containing NO is said to be acid and that containing NO3 is said to be base
NO and NO3 are not acids or bases themselves. However, they can behave as acids or bases in certain reactions. NO can act as an acid when it donates a proton, and NO3 can act as a base when it accepts a proton. Therefore, this statement is correct.

d) NO2 dimerizes to N2O4 with disappearance in paramagnetism
NO2 exists as a brownish gas and contains an unpaired electron, making it paramagnetic. However, at low temperatures, NO2 undergoes dimerization to form N2O4. In the dimer N2O4, the unpaired electrons pair up, resulting in the disappearance of paramagnetism. Therefore, this statement is correct.

In summary, the correct statements about N2O4 are:

- N2O4 is paramagnetic.
- Substance containing NO can act as an acid, and substance containing NO3 can act as a base.
- NO2 dimerizes to N2O4 with the disappearance of paramagnetism.
