Which of the statements given below is incorrect?
A
ONF is isoelectronic with $O_2N^-$
B
$OF_2$ is an oxide of fluorine
C
$Cl_2O_7$ is an anhydride of perchloric acid
D
$O_3$ molecule is bent
Detailed Solution
ONF and $NO_2^-$ both have 24 electrons, so they are isoelectronic.
$OF_2$ is a fluoride of oxygen (oxygen difluoride), not an oxide of fluorine, because fluorine is more electronegative than oxygen — this statement is incorrect.
$2HClO_4 \xrightarrow[-H_2O]{\Delta} Cl_2O_7$, so $Cl_2O_7$ is the anhydride of perchloric acid.
$O_3$ has a lone pair on the central O, so it is bent.
