The correct order of conductivity among (A), (B) and (C) is
(A). 0.1 M HCOOH
(B). 0.1M `CH_(3)` COOH
(C). 0.1M `C_(6)H_(5)` COOH

The pH of a buffer solution of 0.1 M CH_(3)COOH and 0.1 MCH_(3)COONa is (pK_(a)CH_(3)COOH =4.745)

Which out of each pair is expected to be a stornger acid ? (a) CH_(3)COOH" or "HCOOH , (b) CH_(3)COOH" or "C_(6)H_(5)OH (c) C_(6)H_(5)COOH" or "HCOOH , (d) CH_(2)(Cl)COOH" or "CH_(2)(Br)COOH

Which out of each pair is expected to be a stornger acid ? (a) CH_(3)COOH" or "HCOOH , (b) CH_(3)COOH" or "C_(6)H_(5)OH (c) C_(6)H_(5)COOH" or "HCOOH , (d) CH_(2)(Cl)COOH" or "CH_(2)(Br)COOH
