Which of the polyhalide ions is not known?
F−3 does not exist because of absence of d-oribitals in F atom.
Consider the following statements:
S1 : Fluorine does not form any polyhalide because it does not have d-orbitals in valence shell.
S2 : In ClF3, the three lone pairs of electrons occupy the equatorial position.
S3 : In B2 and N2 molecules, mixing of s- and p- atomic orbitals takes place.
Select the correct statements.
