Discussion Overview

The discussion revolves around the concept of nascent oxygen, its formation, reactivity, and its role in chemical reactions. Participants explore its properties, compare it to molecular oxygen, and inquire about related concepts in chemistry.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • Some participants question the stability of monoatomic oxygen and its formation in reactions, suggesting it should exist as O2 instead.
  • Others assert that nascent oxygen has higher reactivity than molecular oxygen and must be generated in situ due to its short-lived nature.
  • There is a discussion about the meaning of "in situ" and its implications for the generation of nascent oxygen in reaction mixtures.
  • Some participants propose that nascent oxygen exists long enough to react with other substances before converting to O2, depending on the reaction dynamics.
  • One participant raises the question of whether other elements can be considered "nascent," noting that the term is primarily associated with hydrogen and oxygen.
  • Another participant shares personal anecdotes about their interest in nascent oxygen and its historical context in their learning.
  • There is curiosity about the characteristics of ozone and its distinct odor compared to O2.
  • A later post inquires whether nascent oxygen can react with atmospheric gases like CO2, CO, and SO2.

Areas of Agreement / Disagreement

Participants express a range of views on the nature and implications of nascent oxygen, with no clear consensus on its properties or the extent of its reactivity. The discussion remains unresolved regarding the broader application of the term "nascent" to other elements.

Contextual Notes

Participants mention various assumptions about the stability and reactivity of nascent oxygen, as well as the conditions under which it is generated. There are references to the competition between reactions involving nascent oxygen and its conversion to O2, which are not fully explored.

Who May Find This Useful

This discussion may be of interest to those studying chemistry, particularly in the areas of reaction mechanisms, the properties of reactive species, and the historical context of chemical terminology.

What is really Nascent Oxygen?
Like in equation
##2KMnO_4 + 3H_2SO_4--> K_2SO_4 + 2MnSO_4+3H_2O+5[O]##
How a mono atomic O is there. It would be unstable, why it is forming? It should have been ##O_2##.
In equation
C2O6H6 + [O]-------> 2CO2 +3H2O]x5
How we are supplying monatomic O?

Nascent oxygen has much higher reactivity than the oxygen bubbled through the reaction mixture. It doesn't stay nascent for long (you are right about it being converted quick to just O2), which is why it has to be generated in situ.

What is situ?
I thought early that situ is a kind of reacting mixture but when looked on Wikipedia, found that there is a Latin phrase in situ which means on the premises. But how we create nascent oxygen and why write in reaction if it quickly converts to O2?
 
Nascent oxygen doesn't convert to O2 instantly, and if it is generated in the reaction mixture it exists for long enough to react with other things present. Conversion to O2 competes with other possible reactions. Sometimes they are too slow and presence of the nascent oxygen doesn't matter, sometimes they are fast and they consume the nascent oxygen before it reacts with itself producing just O2.
 
So are there other things like nascent hydrogen, nascent cobalt, nascent chlorine , nascent sodium etc?
I have heard only nascent word in chemistry used with oxygen most of the times and some time with hydrogen.
 
Technically yes, other elements (reagents) can be "nascent". But it is mostly used for hydrogen and oxygen.

Note that it makes sense only when the "nascent" differs in some way and for some reason from the ordinary thing.
 
Thank you.:)
 
I was expecting some replies from @NascentOxygen . Though I have understood, it would be better that how [O] explains itself.
:smile:

@NascentOxygen is busy learning how to ban those asking difficult questions :biggrin:

Maybe he would have gone to watch Cricket World Cup 2015 in a stadium as he resides in Australia and World Cup has started in Australia?:DD

So this is why my ears were burning ... people talking about me behind my back! :smile:

O1 is a hyperactive species, unstable and short-lived. For this reason, it has to be generated on site where it is needed. :cool:

It is interesting that O3 has such a strong and characteristic odour when O2 (along with most colourless elemental gases) has no odour.

Did you not got the alert of tagging when I first tagged you?
It has been a long time since then.

Just curious to know why you have kept the name NascentOxygen? Are you a expert on it?

Do you know the reason of that?

I first tried to register as NascentHydrogen but the software said that was too many characters, so I settled for my second choice. :smile: I'm not an expert on anything, I'm afraid. :frown:

Nascent oxygen caught my imagination when I first read about it in an old Inorganic Chemistry textbook in a box of books that a uni graduate gave me when I was in primary school. I think I memorized every page in that book, and I still have it.

I read somewhere* that the strong bleaching action of chlorine bleaching powder is actually attributed to the liberation of monatomic oxygen and it's this which performs the bleaching.

I have no idea why ozone has a pungent odour. But, to me as a child, it made my toy trains seem just unreal. :cool::cool:

Replying after quite a time when I see you in other forums. I think you get many alerts as a mentor?
By the way thanks.

Can nascent oxygen absorb (react with) CO2, CO & SO2 from atmosphere?
