Question

Consider the following compounds in the liquid form : $\mathrm{O}_{2}, \mathrm{HF}, \mathrm{H}_{2} \mathrm{O}, \mathrm{NH}_{3}, \mathrm{H}_{2} \mathrm{O}_{2}, \mathrm{CCl}_{4}, \mathrm{CHCl}_{3}$, $\mathrm{C}_{6} \mathrm{H}_{6}, \mathrm{C}_{6} \mathrm{H}_{5} \mathrm{Cl}$.\ When a charged comb is brought near their flowing stream, how many of them show deflection as per the following figure?\

Professor PC Thomas Classes · Answer

(b) : Non-polar compounds which have zero dipole moment will not show any deflection, i.e., $\mathrm{O}_{2}, \mathrm{CCl}_{4}, \mathrm{C}_{6} \mathrm{H}_{6}$ do not show any deflection.\ Only polar compounds having net dipole moment will show deflection when a charged comb is brought near their flowing stream, e.g., $\mathrm{HF}, \mathrm{H}_{2} \mathrm{O}, \mathrm{NH}_{3}, \mathrm{H}_{2} \mathrm{O}_{2}, \mathrm{CHCl}_{3}, \mathrm{C}_{6} \mathrm{H}_{5} \mathrm{Cl}$.
