Chemical Bonding And Molecular Structure Question 103
Question: If HCl molecule is completely polarized, so expected value of dipole moment is 6.12D (deby), but experimental value of dipole moment is 1.03D. Calculate the percentage ionic character [Kerala CET 2005]
Options:
A) 17
B) 83
C) 50
D) Zero
E) 90
Show Answer
Answer:
Correct Answer: A
Solution:
% of ionic character = $ \frac{\text{Experimental value of dipole moment}}{\text{Expected value of dipole moment}} $
$ =\frac{1.03}{6.12}\times 100=16.83%\approx 17% $
