Chemistry Question on Thermodynamics
The highest electrical conductivity of the following aqueous solutions is of:
A
0.1 M difluoroacetic acid
B
0.1 M fluoroacetic acid
C
0.1 M chloroacetic acid
D
0.1 M acetic add
Answer
0.1 M difluoroacetic acid
Explanation
Solution
Fluoro group causes negative inductive effect increasing ionisation, thus 0.1 M difluoroacetic acid has highest electrical conductivity.
