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.
