What is the Difference Between N2O4 and NO2?
🆚 Go to Comparative Table 🆚The main differences between N2O4 and NO2 are their chemical properties, magnetic properties, and physical states. Here are the key differences:
- Chemical Properties: N2O4 is dinitrogen tetroxide, while NO2 is nitrogen dioxide. They are two different chemical compounds with distinct chemical and physical properties.
- Magnetic Properties: N2O4 is diamagnetic, meaning it is not attracted to an external magnetic field. In contrast, NO2 is paramagnetic, indicating that it is attracted to an external magnetic field due to the presence of unpaired electrons.
- Physical State: N2O4 is a colorless liquid, while NO2 is a brown gas.
- Temperature Dependence: The equilibrium between NO2 and N2O4 is temperature-dependent. A decrease in temperature shifts the equilibrium in favor of N2O4, leading to an increase in N2O4. Conversely, heating the system shifts the equilibrium in favor of NO2, making the tube darker.
In summary, N2O4 and NO2 are two distinct chemical compounds with different chemical and physical properties, including magnetic properties and physical states. They also exhibit a temperature-dependent equilibrium, with N2O4 being favored at lower temperatures and NO2 being favored at higher temperatures.
