Arrange the following in decreasing order of their acidic strength. Give  for the arrangement. 

C₆H₅COOH, FCH₂COOH, NO₂CH₂COOH

<p>This is a Short Answer Type Questions as classified in NCERT Exemplar</p><p><strong>NO₂CH₂COOH&nbsp; &gt;&nbsp; FCH₂COOH&nbsp; &gt;&nbsp;C₆H₅COOH</strong></p><p>To begin, determine whether it has an acidic strength associated with it, and whether it is an electron donating or electron withdrawing group. Acidic strength increases as the number of electron withdrawing groups increases. The acidic strength reduces as the electron donating group increases. In decreasing order, the most influential acidic strength is −NO₂&gt;&nbsp;−F&gt;&nbsp;−C₆H₅.</p>
