Question
The fraction of phenol dimerised in benzene if 20 g of phenol in 1 kg benzene exhibits a freezing point depression of 0.69 K. (Kf benzene = 5.12 
), (MW phenol = 94)
), (MW phenol = 94)Options
A.0.74
B.0.37
C.0.46
D.0.64
Solution
ᐃTf = i. kb.m
0.69 = i ×
i = 0.63
for dimerization i = 1 - α/2
0.63 = 1 - α/2
α = 0.74.
0.69 = i ×
i = 0.63
for dimerization i = 1 - α/2
0.63 = 1 - α/2
α = 0.74.
