Question

Which of the following is the wrong statement ?

• A. ONCl and ONO– are not isoelectronic.
• B. O3 molecule is bent
• C. Ozone is violet-black in solid state
• D. Ozone is diamagnetic gas.

Answer 1

[All statement are correct there is no answer]

(1) ONCl = 8 + 7 + 17 = 32e–

ONO– = 8 + 7 + 8 + 1 = 24e– (correct)

(2) Central atom O is sp2 hybridised with 1 lone pair, so bent shape (correct)

(3) Ozone is violet-black in solid state. (Ref. NCERT & shriver atkins)

(4) O3 has no unpaired electrons, so diamagnetic (correct)
