Question

In methane, the replacement of hydrogen by NO₂ is called:

a. Pyrolysis
b. Nitration
c. Halogenation
d. None of these

Answer 1

Nitration is the process of replacing hydrogen by NO₂ in methane.

Step-by-step explanation:

The replacement of hydrogen by NO₂ in methane is called Nitration. In the process of nitration, one or more of the hydrogen atoms in a hydrocarbon are replaced by nitro groups (NO₂). This reaction is commonly used in the synthesis of organic compounds, such as pharmaceuticals and dyes.
