Question

Which of the following is wrong statement?

• A. Ozone is violet-black in solid state
• B. Ozone is diamagnetic gas
• C. ONCl and ONO^- are isoelectronic
• D. O₃ molecule is bent

Answer 1

Answer: (C)

Ozone in solid state is violet-black solid.

All paired electrons, so it is diamagnetic as per Lewis structure.
ONCl – no. of electrons = 32
ONO^– – no. of electrons = 24
They are not isoelectronic.
O₃ has bent structure with Bond angle 116.8^{o .}
