Question

The incorrect statement among the following is

• A. the formal charge on the central oxygen atom of ozone is $+1$
• B. nitrogen dioxide is an odd electron molecule
• C. carbon monoxide and nitrogen are isoelectronic
• D. the van der Waals radius represents the overall size of the atom which excludes its valence shell in a non-bonded situation

Answer 1

Answer: (D)

The formal charges on three oxygen atoms in
$O_3:$
$N{O}_2:$
$CO$ and $N_2$ both have $14$ electrons and hence, are isoelectronic
The van der Waals’ radius is defined as one half the distance between the nuclei of two identical non bonded isolated atoms or two adjacent identical atoms belonging to two neighbouring molecules of an element in the solid state
