Answer Posted / jagadeeshchandra
Generally methanol is not used as a solvent for carbonyl
compounds.Usage of methanol for ketones will produce ketals
and water which gives false result.And aldehydes gives acetals
and water.
pyridine can be used in place of methanol.Halogenated
alcohols,long chain alcohols,Dimethyl formamide can also be
used.
Another thing methanol is reaction part.It forms methyl
sulphite with kf reagent.Whare base will acts as a buffering
agent.
More information i can give.If intrested call me

2. Two grams of Benzoic acid are dissolved in 200 ml of water and extracted with 200 ml of diethyl ether. The distribution coefficient of benzoic acid is 100, and its dissociation constant is 6.5 10-5. Calculate the distribution ratio (D) of benzoic acid at pH 2, 5, and 6. 3. Calculate D at pH 2 to 10 (1 unit apart) in the above problem, and plot D versus pH.
