The highest electrical conductivity of the following aqueous solutions is of
(a) 0.1M acetic acid
(b) 0.1M chloroacetic acid
(c) 0.1M fluoroacetic acid
(d) 0.1M difluoroacetic acid
(d) : Higher the acidity, higher will be the tendency to release protons and hence lighter will be the electrical conductivity. Difluoroacetic acid will be strongest acid due to electron withdrawing effect of two fluorine atoms so as it will show maximum electrical conductivity
