Vedclass · Answer

(B) An odd-electron molecule is one that has an odd number of valence electrons,such as $NO$ (Nitric oxide,$5+6=11$ valence electrons).An expanded octet molecule is one where the central atom has more than $8$ electrons in its valence shell,such as $H_{2}SO_{4}$ (Sulfuric acid).In $H_{2}SO_{4}$,the central sulfur atom is bonded to four oxygen atoms (two double bonds and two single bonds),resulting in $12$ electrons in its valence shell.Thus,the pair containing an odd-electron molecule $(NO)$ and an expanded octet molecule $(H_{2}SO_{4})$ is $NO$ and $H_{2}SO_{4}$.

Which of the following pairs of molecules contains an odd-electron molecule and an expanded octet molecule?
