Q27 / 155 · WBJEE 2025 · Chemistry

Arrange the following compounds in order of their increasing acid strength Figure

  • A
    $I \lt I I \lt I I I \lt I V$
  • B
    $I V \lt I I I \lt I I \lt I$
  • Correct answer
    C
    $I \lt I V \lt I I \lt I I I$
  • D
    $I I \lt I \lt I I I \lt I V$

Solution

As distance decreases -l effect increases, thus acidic strength increases.
