Chemical Bonding And Molecular Structure Question 251
Question: In which compound, the hydrogen bonding is the strongest in its liquid phase [Pb. CET 2001]
Options:
A) $ HF $
B) $ HI $
C) $ CH_4 $
D) $ PH_3 $
Show Answer
Answer:
Correct Answer: A
Solution:
Compound containing highly electronegative element (F, O, N) attached to an electropositive element (H) show hydrogen bonding. Fluorine (F) is highly electronegative and has smaller size. So hydrogen fluoride shows the strongest hydrogen bonding in the liquid phase.
