JEE Main Chemistry question

Not in JEE Main or NEET syllabus

Atomic hydrogen is obtained by:

(A)Electrolysis of heavy water
(B)Reaction of water with heavy metals
(C)Thermal decomposition of water
(D)Passing silent electric discharge through hydrogen at low pressureCorrect

Answer: (D)

Solution

Atomic hydrogen (highly reactive free H atoms) is generated by passing ordinary hydrogen gas through a silent (or arc) electric discharge at low pressure, which supplies enough energy to dissociate the strong H–H bond: $H_2
