Which of the following is the wrong statement?
- ONCl and $ONO^-$ are not isoelectronic
- $O_3$ molecule is bent
- Ozone is violet-black in solid state
- Ozone is diamagnetic gas
The Correct Option is C
Solution and Explanation
(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.

P-Block Elements
- P block elements are those in which the last electron enters any of the three p-orbitals of their respective shells. Since a p-subshell has three degenerate p-orbitals each of which can accommodate two electrons, therefore in all there are six groups of p-block elements.
- P block elements are shiny and usually a good conductor of electricity and heat as they have a tendency to lose an electron. You will find some amazing properties of elements in a P-block element like gallium. It’s a metal that can melt in the palm of your hand. Silicon is also one of the most important metalloids of the p-block group as it is an important component of glass.
P block elements consist of:
- Group 13 Elements: Boron family
- Group 14 Elements: Carbon family
- Group 15 Elements: Nitrogen family
- Group 16 Elements: Oxygen family
- Group 17 Elements: Fluorine family
- Group 18 Elements: Neon family
