Pick out the incorrect statement regarding ozene

Answer»

`O_3` is an emetable, dark-blue diamagnetic gas
The central owygen im `O_(3)` IE `sp^(2)-` hybridized
It is oxidising agent
It does not react with `BaO_(2)`

Solution :`O_(3)` react with KOH to form potassium ozonide, `KO_(3)`, an orange colored solid containing paramagnetic `O_(3)`,
`BaO_(3) +O_(3) to BaO+2O_(2)`
(a). `O_(3)` is an unstable, because its decomposition is exothermic. The blue colour is due to intenstion absorption of red light. It also absorbs strongly in UV region `(lambda=255mm)`
b. In there are three electron pairs (all bonds pairs) AROUND central O atom. To accommodate three electron pairs in trigonal planar orientation (VSEPR THEORY), the central O atom is `sp^(2)-"hybridized"`.
c. In presence of `O_(3)`, Hg is oxidized to a suboxide. If then, starts sticking to glass and loss mobality. This is TERMED as TAILING of mercury.
