Question

A hypothetical covalent molecule, X–Y, has a dipole moment of 1.93 1.93 D and a bond length of 109 pm. 109 pm. Calculate the partial charge on a pole of this molecule in terms of e , e, where e e is the charge on an electron.

Answer 1

Answer:

q= 110.5 ke

Explanation:

Dipole moment is the product of the separation of the ends of a dipole and the magnitude of the charges.

μ = q * d

μ= Dipole moment (1.93 D)

q= partial charge on each pole

d= separation between the poles(109 pm).

e= electronic charge ( 1.60217662 × 10⁻¹⁹ coulombs)

So,

q= $\frac{1.93}{109 * 10^{-12} }$ coulombs

q = $\frac{1.93}{109 * 10^{-12} * 1.60217662 * 10^{-19} }$ e

q = 1.105 * 10⁵ e

q= 110.5 ke
