    Benzoic acid is dissolved in benzene, van't Hoff factor will be

    A)  1                                            

    B)  0.5

    C)  1.5                                        

    D)  2

    Correct Answer: B

    Solution :

                     When benzoic acid dissolve in benzene it will be dimerize due to the intermolecular hydrogen bonding \[2{{C}_{6}}{{H}_{5}}COOH\xrightarrow[{}]{benzene}{{({{C}_{6}}{{H}_{5}}COOH)}_{2}}\] No. of particles after \[vant\text{ }Hoff\text{ }factor=\frac{association\text{ }or\text{ }dissociation}{No.\text{ }of\text{ }particles\text{ }before}\] association or dissociation                                 \[=\frac{1}{2}=0.5\]
