In a polar molecule,the ionic charge is $4.8 \times 10^{-10} \ e.s.u.$ If the inter ionic distance is $1 \ \mathring{A}$,then the dipole moment is ........ $debye$.

Identify the set of molecules which are not in the correct order of their dipole moments.

Which bond angle $\theta$ would result in the maximum dipole moment for the triatomic molecule $XY_2$ shown below?

Which among the following molecules is non-polar?

Dipole moment of $HCl = 1.03 \ D$,$HI = 0.38 \ D$. Bond length of $HCl = 1.3 \ \mathring{A}$ and $HI = 1.6 \ \mathring{A}$. The ratio of the fraction of electric charge,$\delta$,existing on each atom in $HCl$ and $HI$ is
