Each of the following compounds has been dissolved in water to make its 0.001 M solution. Rank them in order of their increasing conductivity in solution (assume $100 \%$ ionisation in each case)

• A

  $c \lt d \lt a \lt b$
• Correct answer
  B

  $c \lt d \lt b \lt a$
• C

  $a \lt b \lt c \lt d$
• D

  $d \lt c \lt a \lt b$

Solution

Greater the number of ions, greater the conduction hence, order of increasing conductivity is

Hence, the correct answer is option: 'B'.
