Given:
Bond distance = 1X10-8 cm
Dipole moment = 1.2 D
To find: Fractional electronic charge on each atom
Formula:
Dipole moment (μ) = electronic charge (e) × bond length (r)
Calculation:
From the formula, we can write:
e = μ / r
Substituting the given values, we get:
e = 1.2 D / (1X10-8 cm)
Converting D to esu (electrostatic unit):
1 D = 3.336X10-30 esu
1.2 D = 3.336X10-30 esu × 1.2 = 4.0032X10-30 esu
Substituting the value of e, we get:
e = 4.0032X10-30 esu / (1X10-8 cm)
Simplifying the expression, we get:
e = 4.0032X10-22
Dividing by the electronic charge of one electron (1.602X10-19 C), we get:
e = 4.0032X10-22 / (1.602X10-19 C)
Simplifying the expression, we get:
e = 0.25
Therefore, the fractional electronic charge on each atom is 0.25.
Answer: Option C
Bond distance = 1X10-8 cm
Dipole moment = 1.2 D

e = 0.25
Therefore, the fractional electronic charge on each atom is 0.25.
