Which of the statements given below is incorrect ?

Options

A. ONF is isoelectronic with `O_(2)N^(-)`
B. `OF_2` is an oxide of fluorine
C. `Cl_2O_7` is an anhydride of perchloric acid
D. `O_(3)` molecule is bent

Answer

B

Explanation

(i) No. of electron in ONF = 24 No. of electron in `NO_2^(-)` = 24 both are isoelectronic
(ii) `OF_2` is a fluoride of oxygen not oxide of fluorine because F.N of fluorine is more than oxygen `OF_2` = oxygen difluoride.
(iii) `Cl_(2)O_(7)` is an anhydride of perchloric acid
`2HClO_(4) overset(Delta)underset(-H_(2)O)to Cl_(2)O_(7)`
(iv) `O_(3)` molecule is bent shape.
