As in the object, what prevent, if any, the ozone to be an anhidride,
forming the H2OO2 acid? |

Oxygen is too electronegative for that to be important, and that
'acid'
would instantly release oxygen. Something like that might indeed
be an intermediate, though, in the decomposition of ozone by water.

Since an anhydride is sopmething that reacts with water to produce an acid,
the hypothetical acid would be H2O4. (Or were you asking why ordinary O2
doesn>t react to produce some sort of H2OO2 acid?) |

My apologies, and nonetheless, my appreciation to all
responders.
I think I can repropose the question in its correct form
as soon as possible, preferably in another similar thread.
Best regards

Apologies to all readers and thanks tall responders.
Below an amended version of what I wanted
to write.]
As in the subject, what prevent, if any,
the ozone from behaving as an anhydride
in water solution, forming at least some
H2OO3 acid like SO2 does?
(albeit H2SO3 is not so stable to be
isolated from aqueous solutions).
IOW, it seems that O3 (OO2) is not a
sufficiently strong Lewis acid to
pick a H2O molecule and rearrange
to form te mentioned Broensted acid,
as do almost all anhydrides.
Any suggestion is welcome

Where do you suggest the electron pair from the water molecule attaches

Of course!
I repeatedly tried to send (through google groups)

BTW, now I seriously doubt that this post could

You can draw a structure for ozone which leaves an empty orbital for
accepting a donor pair, but the fact that it can be drawn does not make it
an energetically feasable structure. Your putative (H2O-O3) adduct will have
formal negative charges on two O atoms, and formal positive charges on the
two bonded to each other. Not likely to be very stable. Note you are
transferring electrons within the molecule - it could be argued that such a
reaction should be viewed as a redox reaction rather than an acid-base
reaction. It is certainly not analogous to water adding to SO2, for example. |
