glucose reacts with the `CH_(3)OH` in the presence of dry HCL gas to form
a) `alpha` - methyl glucoside
b) `beta`- methyl glucoside
c) both a and b
d) pentaacetyl glucose

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

Methyl -alpha-D- glucoside and methyl -beta-D- glucoside are:

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.

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

Lactose is formed by (a) glucose + glucose (b) glucose + galactose (c) glucose + fructose (d) fructose + galactose

Correct the following statements by changing the underlined part of the sentence (Do not change the whole sentence). alpha - D - glucose and beta - D - glucose which differ in the orientation of hydroxyl groups C-1 are called ul ("epimers") ,

Which of the following reactions of glucose can be explained only by its cyclic structure? (a)Glucose forms pentaacetate (b)Glucose reacts with hydroxylamine to form an oxime (c)Pentaacetate of glucose does not react with hydroxyl amine (d)Glucose is oxidised by nitric acid to glyconic acid

Which one of the following is NOT correct for monosaccharides? 1. They are optically active polyhydroxy carbonyl compounds 2.Fructose is ketose sugar and hence it does not give red precipitate with Fehling solution 3. alpha - D(+) glucose and beta - D(+) glucose are anomers 4. Glucose and mannose are anomers
