Verified by Experts

The correct Answer is:
A
Active hydrogen is obtained by passing ordinary hydrogen through an electric arc.
`underset("hydrogen")underset("Molecular")(H_2) underset(2000^@C)overset("Electric arc")to underset("Atomicy drogen")(2H)`
`DeltaH = 104.5 ` Kcal `"mol"^(-1)`
Half-life of atomic hydrogen is 0.3 s. It is very reactive and rapidly combines with other atom to give hydrogen molecule.
