A solution contains 1 g mol. each of p-toluene diazonium chloride and p-nitrophenyl diazonium chloride. To this 1 g mol. of alkaline solution of phenol is added. Predict the major product. Explain your answer.

A solution contains 10 g per dm^3 of urea (molar mass 60 "g mol"^(-1) ) is isotonic with 5% solution of non-volatile solute, M_B of solute is

A solution containing 0.45 g of a urea in 22.5 g of water gave a boiling point elevation of 0.17 K. Calculate the molal elevation constant of water. Molar mass of urea is 60 g "mol"^(-1) .

the protective power of the lyophilic colloids is expressed in terms of gold number, a term introduced by Zsigmondy. Gold number is the number of milli - gram of the protective colloid which prevent the coagulation of 10 mLof red gold sol , when 1 mL of a 10 per cent solution of sodium chloride is added to it . thus smaller the gold number of lyophillic colloid, the greater is the protective power. On addition of one mL of sloution of 10 % NaCl to 10 mL. of red gold sol in presence of 0.025 g of starch the coagultion is just prevented . the gold number of starch is : 0.025, 0.25, 2.5, 25.

A 1 litre solution containing NH_(4)Cl and NH_(4)OH has hydroxide ion ion concentration of 10^-6) mol//litre. Which of the following hydroxides could be precipitated when the solution is added to 1 litre solution of 0.1 M metal ions? (I) Ba(OH)_(2)(K_(sp)=5xx10^(-3)) , (II) Ni(OH)_(2)(K_(sp)=1.6xx10^(-16)) (III) Mn(OH)_(2) (K_(sp)=2xx10^(-13)) , (IV) Fe(OH)_(2) (K_(sp)=8xx10^(-16))

Dissolving 120g of urea (mol.wt 60) in 1000g of water gave a solution of density 1.15g/ml. The molarity of solution is:

Specific conductance of 0.1M sodium chloride solution is 1.06×10-2 ohm-1 cm-1. Its molar conductance in ohm-1cm2 mol-1 is

Calculate the volume of 0.1 M NaOH solution required to neutralize the solution produced by dissolving 1.1 g of P_4O_6 in water.

If 1/6 sin theta, cos theta and tan theta are in G.P. then the general solution for theta is

For a dilute solution containing 2.5 g of a non volatile non electrolyte solution in 100 g of water, the elevation in boiling point at 1 atm pressure is 2^@C . Assuming concentration of solute is much lower than the concentration of solvent, the vapour pressure (take k b = 0.76 K Kg mol^-1 )
