• # question_answer Acetic acid exists in benzene solution in the dimeric form. In an actual experiment the van't Hoff factor was found to the$0.52$. Then the degree of dissociation of acetic acid is A)  $0.48$                       B)  $0.88$C)  $0.96$            D)  $0.52$

$\begin{matrix} 2C{{H}_{3}}COOH \\ 1 \\ 1-a \\ \end{matrix}\begin{matrix} {{\left( C{{H}_{3}}COOH \right)}_{2}} \\ 0 \\ {\scriptstyle{}^{a}/{}_{2}} \\ \end{matrix}$ $i=1-\frac{\alpha }{2}$ $\alpha =2(1-i)$ $=2(1-0.52)=0.96$
