JEE Advanced 2020 — Paper 2 — Question 18

Consider the following compounds in the liquid form:

$\mathrm{O}_{2}$ , $\mathrm{HF}, \mathrm{H}_{2} \mathrm{O}, \mathrm{NH}_{3}, \mathrm{H}_{2} \mathrm{O}_{2}, \mathrm{CCl}_{4}, \mathrm{CHCl}_{3}, \mathrm{C}_{6} \mathrm{H}_{6}, \mathrm{C}_{6} \mathrm{H}_{5} \mathrm{Cl}$ .

cWhen a charged comb is brought near their flowing stream, how many of them show deflection as per the

following figure?

Answer: 6

Numerical answer — enter this value.

Step-by-step solution

Only polar molecules can be attracted by a charged comb. So, except $\mathrm{O}_{2}, \mathrm{CCl}_{4}$ and $\mathrm{C}_{6} \mathrm{H}_{6}$ all can be

attracted in electric field.
