Chemical Bonding And Molecular Structure Question 97
Question: In a polar molecule, the ionic charge is $ 4.8\times {10^{-10}} $ e.s.u. If the inter ionic distance is one Å unit, then the dipole moment is [MH CET 2003]
Options:
A) 41.8 debye
B) 4.18 debye
C) 4.8 debye
D) 0.48 debye
Show Answer
Answer:
Correct Answer: C
Solution:
Given ionic charge $ =4.8\times {10^{-10}} $ e.s.u. and ionic distance $ =1A{}^\circ ={10^{-8}}cm $ we know that dipole moment = ionic charge × ionic distance $ =4.8\times {10^{-10}}\times {10^{-8}} $
$ =4.8\times {10^{-8}} $ e.s.u. per cm $ =4.8 $ debye.
