Chemistry - CHEMICAL BONDING Question with Solution | TestHub

Dipole moment, $(\mu )=\delta \times d$ where, $\delta =$ magnitude of electric charge $d=$ distance between particles (or bond length) $$\begin{array}{l}\therefore \delta =\frac{\mu }{d}\\ \begin{array}{rl}\text{ or }& \frac{{\delta }_{\mathrm{HCl}}}{{\delta }_{\mathrm{HI}}}=\frac{{\mu }_{\mathrm{HCl}}}{d_{\mathrm{HCl}}}\times \frac{d_{\mathrm{HI}}}{{\mu }_{\mathrm{HI}}}\\ & =\frac{1.03\times 1.6}{1.3\times 0.38}=3.3:1\end{array}\end{array}$$
