Question

Consider the following compounds in the liquid form : 

O₂, HF, H₂O, NH₃, H₂O₂, CCl₄, CHCl₃, C₆H₆, C₆H₅Cl. 

When a charged comb is brought near their flowing stream, how many of them show deflection as per the following figure?

Answer 1

Answer: 6

Here polar molecules in the liquid form will be attracted/deflected near charged comb.

Polar molecules : HF, H₂O, NH₃, H₂O₂, CHCl₃, C₆H₅Cl (6-polar molecules) 

Nonpolar molecules : O₂, CCl₄, C₆H₆
