Answer #1

1)=Q*r

where =dipole moment of the bond =0.44D

Q=magnitude of charge

r=bond length=1.61*10^-10m

1Cm=2.9979 *10^29 D

also 1A=10^-10m

now =0.44D * 1/2.9979 *10^29 D/Cm=0.1468 * 10^-29 Cm

so Q=/r=0.1468 * 10^-29 Cm/1.61*10^-10m=0.091161 * 10^-19 C=9.1161 *10^-21C

2)% ionic character=observed/(100% ionic) * 100

(for electron and proton separated by 1 A,=4.80D

=(1.69 * 10^-19 C) * 10^-10m=1.60 * 10^-29Cm=4.80 D)

For 100 % ionic H-I bond 1A apart=1.61/1 *4.80D=7.728D

% ionic character=0.44/7.728 * 100=5.69%
