Which of the following is an example of super octet molecule ?
1 \({\rm{Cl}}{{\rm{F}}_{\rm{3}}}\)
2 \({\rm{PC}}{{\rm{l}}_{\rm{5}}}\)
3 \({\rm{I}}{{\rm{F}}_{\rm{7}}}\)
4 All of these
Explanation:
Due to availability of vacant d - orbitals.

It is believed that atoms combine with each other such that the outermost shell acquires a stable configuration of 8 electrons.If stability were attained with 6 electrons rather than 8,what would be the formula of the stable flouride ion?
1 \({{\rm{F}}^ - }\)
2 \({{\rm{F}}^{\rm{ + }}}\)
3 \({{\rm{F}}^{{\rm{2 + }}}}\)
4 \({{\rm{F}}^{{\rm{3 + }}}}\)
Explanation:
Number of valence electrons in F are 7.Thus,in order to have 6 valence electrons ,it must lose one electron and thus it would have the formula \({{\rm{F}}^{\rm{ + }}}\)
In \({{\rm{B}}_{\rm{2}}}{{\rm{H}}_{\rm{6}}}\) two three-centre two-electron bond exist due to electron deficiency on boron atom. Also it is more electropositive than others.
