Chemical Bonding And Molecular Structure Question 455
Question: KF combines with HF to form $ KHF_2 $ . The compound contains the species
Options:
A) $ {K^{+}},{F^{-}} $ and $ {H^{+}} $
B) $ {K^{+}},{F^{-}} $ and HF
C) $ {K^{+}} $ and $ {{[HF_2]}^{-}} $
D) $ {{[KHF]}^{+}} $ and $ F_2 $
Show Answer
Answer:
Correct Answer: C
Solution:
- Since F form H-bond $ {{[HF_2]}^{-}} $ exists.
Therefore $ KHF_2 $ gives $ {K^{+}}+HF_2^{-} $
