What fraction of charge is present on iodine in covalently bonded `H^(delta+) - I^(delta - )` if the dipole moment of HI is 0.38 D and the bond length is 1.61 Å.

A

0.05

B

0.16

C

0.33

D

0.79

Text Solution

Verified by Experts

The correct Answer is:
A
`mu = e xx d , 0.38 xx 10^(-18) esu cm = x xx 4.8 xx 10^(-10) esu xx 1.61 xx 10^(-8) cm rArr x = (0.38)/(1.61 xx 4.8) = 0.5`
