Question

A diatomic molecule has a dipole moment of \( 1.2 \, D \). If the bond distance is \( 1 \, \text{Å} \), then fractional charge on each atom is ______ \( \times 10^{-1} \, \text{esu} \).
(Given \( 1 \, D = 10^{-18} \, \text{esu cm} \))

Answer 1

Correct Answer: 0

The dipole moment \(\mu\) is given by:

\[ \mu = q \times d \]

Substitute the values:

\[ 1.2 \times 10^{-10} \, \text{esu} \cdot \text{Å} = q \times 1 \, \text{Å} \] \[ q = 1.2 \times 10^{-10} \, \text{esu} \]

Thus, the fractional charge on each atom is:

\[ 0 \times 10^{-1} \, \text{esu}. \]
