H-Cl 결합의 이온결합성 백분율. 1.03 D 127 pm

The dipole moment of HCl is 1.03 D,

if H–Cl bond distance is 1.27 Å,

what is the percentage of ionic character in the H–Cl bond?

The dipole moment of HCl is 1.03 D,

and the bond length is 127 pm.

What is the percent ionic character of the HCl bond?

---------------------------------------------------

dipole moment, μ = Q × r (단위: D)

( 참고 https://ywpop.tistory.com/2581 )

1 D = 3.336×10^(-30) C•m

1 Å = 10^(-10) m 이므로,

1.27 Å × (10^(-10) m / 1 Å) = 1.27×10^(-10) m

1 pm = 10^(-12) m 이므로,

127 pm × (10^(-12) m / 1 pm) = 127×10^(-12) m

μ(theoretical) = Q × r

= (1.60×10^(-19) C) (1.27×10^(-10) m) (1 D / 3.336×10^(-30) C•m)

= (1.60×10^(-19) C) (127×10^(-12) m) (1 D / 3.336×10^(-30) C•m)

= (1.60×10^(-19)) (127×10^(-12)) (1 / (3.336×10^(-30)))

= 6.09 D

percentage of ionic character

= [μ(experimental) / μ(theoretical)] × 100

= [1.03 D / 6.09 D] × 100

= 16.9%

답: 16.9%

[참고] 전자(e^-) 1개의 전하량 = 1.60×10^(-19) C
