8 A stream of liquid from a burette is deflected by a charged rod.
Which substance, in its liquid state, will be deflected the most?
A C5H12
B CCl4
C BCl3
D CH2Cl2
ANSWER
D CH2Cl2
Analysis of Option/Explanation
Remember only polar molecules will deflect.
Option A
C5H12 is an alkane and non polar.
Option B
Here chlorine is polar, but positions of Chlorine opposite to each other cancel each other effect, hence non polar.
Option C
BCl3 is also non polar.
Option D
CH2Cl2 is polar hence it will deflect. Therefore, Option D is correct answer.
