Vedclass · Answer

(B) To determine if a molecule is paramagnetic,we check for the presence of unpaired electrons in its molecular structure.$1$. $Cl_2O$: Chlorine is in the $+1$ oxidation state. The total number of valence electrons is $7 + 6 + 7 = 20$. All electrons are paired.$2$. $ClO_2$: Chlorine is in the $+4$ oxidation state. The total number of valence electrons is $7 + 6(2) = 19$. Since the total number of valence electrons is odd,there must be at least one unpaired electron,making it paramagnetic.$3$. $Cl_2O_7$: Chlorine is in the $+7$ oxidation state. All valence electrons are involved in bonding and are paired.$4$. $Cl_2O_6$: In the solid state,it exists as an ionic dimer $[ClO_2]^+[ClO_4]^-$,where all electrons are paired.Therefore,$ClO_2$ is paramagnetic.
