MCQ
Which of the following pair of molecules contain odd electron molecule and an expanded octet molecule?
- ✓$BCl _{3}$ and $SF _{6}$
- B$NO$ and $H _{2} SO _{4}$
- C$SF _{6}$ and $H _{2} SO _{4}$
- D$BCl _{3}$ and $NO$
✓
Answer
Correct option: A.
$BCl _{3}$ and $SF _{6}$
(A) $BCl _{3} \rightarrow$ Even Electron molecule
$SF _{6} \rightarrow$ Expanded octet molecule
(B) $NO \rightarrow$ Odd Electron molecule
$H _{2} SO _{4} \rightarrow$ Expanded octet.
(C) $SF _{6} \rightarrow$ Even Electron molecule
$H _{2} SO _{4} \rightarrow$ Expanded octet.
(D) $BCl _{3} \rightarrow$ Even Electron molecule
$NO \rightarrow$ Odd Electron molecule
$S \rightarrow 12e^{-}$ in outer orbit.
