Difference Between Nascent (Atomic) and Molecular Hydrogen
Class : 11
Nascent Hydrogen :
A reactive form of hydrogen generated in situ in the reaction mixture (e.g. by the action of acid on zinc). Nascent hydrogen can reduce elements and compounds that do not readily react with 'normal' hydrogen. It was once thought that the hydrogen was present as atoms, but this is not the case. Probably hydrogen molecules are formed in an excited state and react before they revert to the ground state.
Molecular Hydrogen :
The normal form of hydrogen gas found on Earth, with two hydrogen atoms bound together by two shared electrons. Hydrogen molecules cannot survive in most regions of space, because they are easily dissociated (split) by ultraviolet light from stars, but they do occur in cold, dense molecular clouds where they are shielded by dust particles. Molecular hydrogen is the main constituent of molecular clouds, but it is difficult to observe directly as it is a symmetrical molecule with no strong radio or millimetre-wave spectral lines.
Difference between Nascent Hydrogen and Molecular Hydrogen
- Nascent Hydrogen is the newly born hydrogen in the viscinity of metal surface from which it is formed but Hydrogen molecule collected in the gas jar or else where
- Nascent Hydrogen in in its atomic stat and represented by H but Molecular hydrogen is in the molecular state and is represented by H2.
- Nascent Hydrogen can not exist independently but Molecular Hydrogen can exist independently.
- Nascent Hydrogen is more reactive and Hydrogen gas is less reactive comparatively.
