(a) \(ONCl= 8+ 7+ 17= 32e^-\) \(ONO = 8 + 7 + 8 + 1 = 24e^-\) (correct)
(b) Central O-atom is \(sp^2\)-hybridised with 1 lone pair, so bent shape (correct).
(c) In solid state, ozone is violet-black. Ozone does not exist in solid state, thus incorrect.
(d) \(0_3\) has no unpaired electrons, so diamagnetic (correct).
Hence, the correct option is (C): Ozone is violet-black in solid state.
20 mL of sodium iodide solution gave 4.74 g silver iodide when treated with excess of silver nitrate solution. The molarity of the sodium iodide solution is _____ M. (Nearest Integer value) (Given : Na = 23, I = 127, Ag = 108, N = 14, O = 16 g mol$^{-1}$)
