Which of the following is the wrong statement ?

AONCl and ONO^- are not isoelectronic.BO_3 molecule is bentCOzone is violet-black in solid stateDOzone is diamagnetic gas.

Show answer and solution▾

(1) ONCl = 8 + 7 + 17 = 32e^-
ONO- = 8 + 7 + 8 + 1 = 24e^- (correct)
(2) [IMAGE] Central atom O is sp^2 hybridised with
1 lone pair, so bent shape (correct)
(3) Ozone is violet-black in solid state.
(4) O_3 has no unpaired electrons, so diamagnetic (correct)
(1) ONCl = 8 + 7 + 17 = 32e^-
ONO- = 8 + 7 + 8 + 1 = 24e^- (lgh)
