JEE Advanced2013Chemistryp Block Elements (Group 15, 16, 17 & 18)Actual
The correct statement(s) about O 3 is(are)
Options
- AO-O bond lengths are equal.
- BThermal decomposition of O 3 is endothermic.
- CO 3 is diamagnetic in nature.
- DO 3 has a bent structure.
Correct answer
A. O-O bond lengths are equal.
Step-by-step solution
In ozone due to resonating structures O - O bond lengths are same O-O bond lengths are equal is correct 2 O 3 ⟶ 3 O 2 + 6 8  Kcal It is exothermic decomposition (O 3 unstable). Thermal decomposition of O 3 is endothermic is wrong O 3 is diamagnetic in nature Is correct due to all paired electrons. O 3 has a bent structure Is correct with a bond angle of 116.8 o and bent structure
