This section contains some integer type question Estimate the percent ionic character of the HBr molecule, given that the dipole moment `(mu)` is 0.63 D and HBr bond length 187.5 pm

Answer» Correct Answer - 7
Calculated value of `mu=exxl`
`=4.8xx10^(-10)esuxx187.5 xx10^(-10)cm`
`=9xx10^(-18)esu cm `
`(1xx10^(-18)esu-cm=1"Debye")=9 Debye`
Observed value of `mu=0.63` debye ltbr. % ionic character =`("Observed value x 100)/("calculated value")`
`=0.63/9xx100=7%`
