Phenols are more acidic than phenols because delocalization of electrons takes place in phenols by resonance .
Phenol loses its hydrogen to form the phenoxide ion which resonates and stabalizes itself ,thus this loss of electrons makes phenol more acidic than alcohols.

Given:
Kf = 3.83 K kg mol-1
Mass of solute = 2.56 gt
Mass of solvent = 100 g
Therefore,
Molality of the solution, {tex}m=\frac{2.56}{32} \times \frac{1000}{100}=0.8 m{/tex}
The depression in freezing point of a solution is given as
{tex}\Delta \mathrm{Tf}{/tex} = iKfm
0.383 = i {tex}\times{/tex}3.83 {tex}\times{/tex} 0.8
i = {tex}\frac {1} {8}{/tex}
Hence, 8 sulphur atoms are undergoing association, as shown below:
