54.Glucose reacts with `CH_(3)OH` in the presence of dry `HCl` gas to form 1)` alpha -methyl glucoside` 2) `beta -methyl glucoside` 3) Both (1) and (2). 4)` pentaacetyl glucose`

Glucose when treated with CH_3 OH in the presence of dry HCl gives alpha and beta -methylglucosides because it contains

D-glucose, on treating with methanol in presence of dry HCl gives methyl glucosides according to the following reaction. Mention true (T) and False from the following statements S_(1) : The glucosides do not reduce fehling's solution S_(2) : The glucosides do not react with hydrogen cyanide or hydroxylamine S_(3) : Behaviour of glucosides as stated in S_(1) and S_(2) indicates the absence of free -CHO group S_(4) : The two forms of glucosides are enantiomers.

The heating of oxime of acetone in presence of conc. H_(2)SO_(4) to form N - methyl ethanamide is called

Phenol reacts with methyl chloroformate in the presence of NaOH to form product A. A reacts with Br_(2) to form product B. A and B are respectively

cos 2 alpha =(3 cos 2 beta -1)/( 3-cos 2 beta), then tan alpha=

Unlike glucose, neither alpha nor beta -methyl glucoside reduces Tollens' reagent or Fehling solution. Why?

If amixture of Na_(2)CO_(3) and NaOH in equimolar quantities when reacts with 0.1 M HCl in presence of phenolphthalein indicator consumes 30 ml of the acid. What will be the volume (in mL) of 0.15 M H_(2)SO_(4) used in the separate titration of same mixture in presence of methyl orange indicator.

A 5.2 molal aqueous of methyl alcohol, CH_(3)OH , is supplied. What is the molefraction of methyl alcohol in the solution ?
