Which of the following will not conduct electricity in aqueous solution?

Which of the following,when dissolved in water,forms a solution that is non-conducting?

The degree of dissociation of $0.1 \ N$ $CH_3COOH$ is (given $K_a = 1 \times 10^{-5}$) approximately $......$

What is the concentration of $[H_3O^{+}]$ ion in $mol \ L^{-1}$ of $0.001 \ M$ acetic acid $(\alpha = 0.134)$?

$A$ weak monobasic acid is $10 \%$ dissociated in $0.05 \ M$ solution. What is its percentage dissociation in $0.10 \ M$ solution (in $\%$)?

If $\alpha$ is the degree of ionization,$C$ is the concentration of a weak electrolyte,and $K_a$ is the acid ionization constant,then the correct relationship between $\alpha$,$C$,and $K_a$ is:
