JEE Advance - Chemistry (2020 - Paper 2 Offline - No. 2)
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?
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
6
Explanation
Only polar liquid will be attracted towards charged comb due to the formation of electrically charged droplets in the polar liquid stream, induced by a nearby charged object. Hence, liquid showing deflection are HF, H2O, NH3, H2O2, CHCl3, C6H5Cl.
