Question

Calculate the % of ionic character of a bond having length = 0.92 Å and 1.91 D as its observed dipole moment.

• A. 43.25
• B. 86.5
• C. 8.65
• D. 43.5

Answer 1

Answer: (A)

43.25

Answer 2

Calculated μ considering 100% ionic bond [When we consider a compound ionic, then each ionic sphere should have one electron charge on it of $4.80 \times 10^{- 10}esu$ (in CGS unit) or $1.60 \times 10^{- 19}C$ (in SI unit)]

= 4.8 × 10^–10 × 0.92 × 10^–8 esu cm = 4.416 D

% Ionic character $= \frac{1.91}{4.416} \times 100 = 43.25.$
