Question

The most reactive state of hydrogen is

• A. Atomic hydrogen
• B. Heavy hydrogen
• C. Molecular hydrogen
• D. Nascent hydrogen

Answer 1

The correct option is A Atomic hydrogen

1) Atomic hydrogen

2) Atomic hydrogen is extremely reactive, being more reactive than ordinary, nascent, or adsorbed oxygen.

3) When it is passed over metals or non-metals, it forms hydrides at normal temperatures, excepting for nitrogen, to which it does not react.

4) Atomic hydrogen is an extremely powerful reducing agent, reducing oxides chlorides and sulphides of some metals like Ag, Hg, Cu etc. to metals at ordinary temperature.
