Which of the following statement given below is incorrect?

Options

A. `ONF` is isoelectronic with `O_(2)N^(-)`
B. `OF_(2)` is an oxide of fluorine
C. `Cl_(2)O_(7)` is an anhydride of perchloric acid
D. `O_(3)` molecule is bent

Answer

2

Explanation

Fluorine forms two binary compounds with oxygen I.e, `OF_(2)` and `O_(2)F_(2)` However they are called as oxygen fluroides rather than oxides of fluoride since the electronegativity fo `F` is higher than that of `O`.
(1) Both `ONF (8+7+9=24)` and `NO_(2)^(-) (7+8+8+1=24)` are isoelectronic.
(2) as they have some `MO` configuration due to same total number of electrons.
(3) `Cl_(2)O_(7)` is an anhydride of perchloric acid
`Cl_(2)O_(7)+H_(2)Orarr2HClO_(4) overset(-H_(2)O)underset(Delta)rarrCl_(2)O_(7)`
`O_(3)` molecules (steric number : `2+1`) is bent `//`angular in shape.
