Short Answer TypeArrange the following compounds in an increasing order of their solubility in water:
C6H5NH2, (C2H5)2NH, C2H5NH2Explain the following giving one example for each:
(i) Reimer-Tiemann reaction.
(ii) Friedel Craft’s acetylation of anisole.
How would you obtain
(i) Picric acid (2, 4, 6-trinitrophenol) from phenol,
(ii) 2-Methylpropene from 2-methylpropanol?
(i) Phenol on reaction with concentrated HNO3 results in the formation of 2,4,6-Trinitrophenol or Picric acid. 
ii) 2-methyl propene can be obtained from 2-methyl propanol by the reaction of the later with alc. KOH.
What is essentially the difference between α-form of glucose and β-form of glucose? Explain.
Long Answer Type(a) Differentiate between molarity and molality for a solution. How does a change in temperature influence their values?
(b) Calculate the freezing point of an aqueous solution containing 10.50 g of MgBr2in 200 g of water. (Molar mass of MgBr2 = 184 g) (Kf for water = 1.86 K kg mol-1)
