Show that for dimerisation of benzoic acid in benzene solution, degree of association, = 2(1-i) where I = Van't Hoff factor.

Benzoic acid under goes dimenization in benzene solution, the Van't Hoff factor related to the degree of associatioin 'x' of the acid as.

A 1 molal aquous solution of trichloroacetic acid (C Cl_3COOH) is heated to its boiling point. The solution has the boiling point of 100.18^@C . Determine the Van't Hoff factor for the acid ( k_b for water = 0.512)

A 1.2% solution of NaCl is isotonic with 7.2% solution of glucose. Calculate Van't Hoff factor of NaCl solution.

Give examples to show that : A^2=I , where A ne I

On dissolving 19.5g CH_2F COOH in 500g of water, a depression of 1^@C in freezing point of water is observed. Calculate the vant Hoff factor and dissociation constant of Fluoroacetic acid. (Given, K_f = 1.86 K kg mol^-1)

Benzoic acid completely dimerises in benzene. What will be the vapour pressure of a solution containing 61g of benzoic acid per 500g benzene when the vapour pressure of pure benzene at the temperature of experiment is 66.6 Torr?

Form the pair of linear equations in the following problems,and find their solutions(if they exist) by the elimination method:(i)If we add 1 to the numerator and subtract 1 from the denominator a fraction reduces to 1.It becomes 1/2 if we only add 1 to the denominator.What is the fraction?

How will bring about following conversions? (any five) (i) Acetone to ethylene glycol ketal. (ii) p-fluorotoluene to p-fluoro benzaldehyde (iii) Propanoyl chloride to bute-2 one). (iv) 3-Nitrobromobenzene to 3-nitro benzoic acid. (v) Benzaldehyde to a-hydroxy phenylacetic acid. (v) Benzaldehyde to a-hydroxy phenylacetic acid. (vi) Benzene 1,2 dioic acid to phthalimide.

A 0.561 m solution of an unknown electrolyte depresses the freezing point of water by 2.93^@C . What is Vant Hoff factor for this electrolyte? The freezing point depression constant (K_f) for water is 1.86^@C Kg mol^-1 .
