JEE MAIN - Chemistry (2005 - No. 35)
The highest electrical conductivity of the following aqueous solutions is of :
0.1 M acetic acid
0.1 M chloroacetic acid
0.1 M fluoroacetic acid
0.1 M difluoroacetic acid
Forklaring
Thus difluoro acetic acid being strongest acid will furnish maximum number of ions showing highest electrical conductivity. The decreasing acidic strength of the carboxylic acids given is difluoro acetic acid $$>$$ fluoro acetic acid $$>$$ chloro acitic acid $$>$$ acetic acid.
