🤓 Based on our data, we think this question is relevant for Professor Al-Qaisi's class at UMD.

The HCl(g) molecule has a bond length of 127 pm and a dipole moment of 1.08 D.

Without doing detailed calculations, determine the best estimate for its percent ionic character.

In this problem, **we are asked to determine the best estimate of the percent ionic character of the HCl(g) molecule.**

Recall, that a **dipole moment (µ) **occurs any time there is a separation of positive and negative charge.

It is expressed mathematically:

$\overline{){\mathbf{\mu}}{\mathbf{=}}{\mathbf{qr}}}$

Where:** µ (in Debye) ** is the dipole moment, **q (1.6 x 10 ^{-19} C) **is the charges, and

The **percent ionic character **is **the ratio between the bond's actual dipole moment to the dipole moment it would have if electrons were completely transferred from one atom to another, multiplied by 100%.**

$\overline{){\mathbf{Percent}}{\mathbf{}}{\mathbf{ionic}}{\mathbf{}}{\mathbf{character}}{\mathbf{=}}\frac{{\mathbf{\mu}}_{\mathbf{measured}}}{{\mathbf{\mu}}_{{\mathbf{e}}^{\mathbf{-}}\mathbf{}\mathbf{is}\mathbf{}\mathbf{completely}\mathbf{}\mathbf{transferred}}}{\mathbf{\times}}{\mathbf{100}}{\mathbf{\%}}}$

To solve this problem, let us assume that this molecule is completely ionic.
