Question

Which of the statements given below is incorrect ?

ONF is isoelectronic with $O_2 N^-$

$OF_2$ is an oxide of fluorine

$Cl_2O_7$ is an anhydride of perchloric acid

$O_3$ molecule is bent

Answer

$OF_2$ is an oxide of fluorine

Explanation

Solution

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 EN of fluorine is more than oxygen
${OF_2}$ = oxygen difluoride
(iii) ${Cl_2O_7}$ is an anhydride of perchloric acid
${2HClO_4 ->[\Delta][-H_2O] Cl_2 O_7}$
(iv) ${O_3}$ molecule is bent
