#HCl, HNO_3, H_3PO_4, HNO_2, H_3BO_3#

Explanation:

Conductivity is given maily by #H^+# ions. You have two strong acid fully dissociated that have the greater conductivity. HCl is more conductive than #HNO_3# but the difference is very small. the later compounds are in order of their acid force # H_3PO_4 with K_1 =7 xx 10^-3, HNO_2 with K =5 xx 10^-4, H_3BO_3 with K= 7 xx 10^-10#
