Question

Pure benzene freezes at 5.3°C. A solution of 0.223 g of phenylacetic acid (C H CH COOH) in 4.4 g of benzene (K = 5.12 K kg mol ) freezes at 4.47°C. From this observation, one can conclude that (A) phenylacetic acid exists as such in benzene (B) phenylacetic acid undergoes partial ionization in benzene (C) phenylacetic acid undergoes complete ionization in benzene (D) phenylacetic acid dimerizes in benzene 6 5 2 f –1
