MCQ

Consider the following compounds in the liquid form :

$O _2, HF , H _2 O , NH _3, H _2 O _2, CCl _4, CHCl _3, C _6 H _6, C _6 H _5 Cl \text {. }$

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

✓
$6$
B
$8$
C
$9$
D
$10$

✓

Answer

Correct option: A.

$6$

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

Polar molecules : $HF , H _2 O , NH _3, H _2 O _2, CHCl _3, C _6 H _5 Cl$ ($6$-polar molecules)

Nonpolar molecules : $O _2, CCl _4, C _6 H _6$
