1.22 g C_6H_5COOHis added to two solvents. (i) In 100 g CH_3COCH_3 , Delta T_b = 0.17 , K_b = 1.7 kg K "mol"^(-1)(ii) In 100 g C_6H_6 , Delta T_b = 0.13 , K_b = 2.6 kg K "mol"^(-1) Find out the molecular weight of C_6H_5COOH in both the solvents and interpret the result. |

Answer» Solution :APPLY `Delta T_b = K_b` .m in both CASES (i) 122 (II) 244, `C_6H_5COOH` dimerises in `C_6H_6` |
