Question

the dipole moment of HCl is 3.6×10^-30 and interatomic distance is 1 armstrong . the % ionic character of HCl is

Answer 1

“we know ,
HBr is an ionic compound in which H has + 1 and Br has -1 ion” 
“dipole moment = Charge x distance between them” 
“=1.6 x 10^-19 x 141 x 10^-12 Cm”
“=225.6 x 10^-31 Cm”
“=22.56 x 10^-30 Cm”

now,
Percentage of ionic characters 
“=dipole moment by experimental/dipole moment by theoretical x100”
“=(2.6 x 10^-30/22.56 x 10^-30 ) x 100”
“=260/22.56 %”
“=11.52 %”
