Chemical Bonding And Molecular Structure Question 435
Question: Which of the correct increasing order of lone pair of electrons on the central atom-
Options:
A) $ IF_7<IF_5<ClF_3<XeF_2 $
B) $ IF_7<XeF_2<ClF_2<IF_5 $
C) $ IF_7<ClF_3<XeF_2<IF_5 $
D) $ IF_7<XeF_2<IF_5<ClF_3 $
Show Answer
Answer:
Correct Answer: A
Solution:
- The number of lone pairs of electrons on central atom in various given species are Species Number of lone pairs on central atom $ IF_7 $ Nil $ IF_5 $ 1 $ ClF_3 $ 2 $ XeF_2 $ 3 Thus the correct increasing order is $ \begin{aligned} & IF_7<IF_5<ClF_3<XeF_2 \\ & 0123 \\ \end{aligned} $
