JEE Mains · Chemistry · STD 11 - 4. Chemical bonding and molecular structure
Which of the following is the wrong statement?
- A \(ONCl\) and \(ONO^-\) are isoelectronic.
- B \(O_3\) molecule is bent
- C Ozone is violet-black in solid state
- D Ozone is diamagnetic gas.
Answer & Solution
Correct Answer
(A) \(ONCl\) and \(ONO^-\) are isoelectronic.
Step-by-step Solution
Detailed explanation
(a) Number of electrons in \(\begin{array}{l}\mathrm{ONCl}=3.2 \mathrm{e}^{-} \\\mathrm{ONO}^{-}=24 \mathrm{e}^{-}\end{array}\) Thus, ONCl and ONO- are not isoelectronic. (b) \(\mathrm{O}_{3}\) has bent shape structure. Central atom O is \(s p^{2}\) hybridised with 1 lone pair…
