Question

Hydrogen is not more reactive at ordinary temperature, because at ordinary temperature it is in its:

• A. gaseous state
• B. liquid state
• C. molecular state
• D. atomic state

Answer 1

The correct option is C molecular state

Hydrogen is not reactive at ordinary temperature because it is in molecular state i.e., as $H_2$ with its complete duplet which makes it stable and lesser reactive. At very high temperature, hydrogen exists in atomic form having one electron i.e., incomplete duplet which makes it less stable and highly reactive.
