Which L-sugar on oxidation gives an optically active dibasic acid ( 2 COOH groups)?

Detailed Solution for Test: Preparation and Reactions of Glucose - Question 2
Any sugar will be optically active when it does not have any plane of symmetry. As only (a) \& (d) are L-sugar, (b) \& (c) are D-sugar after oxidation.
(a) (Refer to Image 1) - The product do not superimpose in its mirror image.
(d) (Refer to Image 2) - As it has plane of symmetry.

Hydrolysis of sucrose with dilute aqueous sulphuric acid yields
Detailed Solution for Test: Preparation and Reactions of Glucose - Question 4
On hydrolysis with dilute aqueous sulphuric acid, sucrose gives a equimolar mixture of D-(+) glucose and D-(-)-fructose.

D-(+) glucose D-(-) fructose 1 : 1 arter hydrolysis
Sucrose is dextrorotatory but after hydrolysis gives dextrorotatory and laevorotatory fructose, laevorotatory fructose is more, so the mixture is laevorotatory.

In osazone formation, glucose reacts with three molecules of phenylhydrazine. Which statement is true regarding this?
Detailed Solution for Test: Preparation and Reactions of Glucose - Question 5
First molecule of phenylhydrazine unedrgoes nucleophilic addition on carbonyl (- CHO in glucose and in fructose) group. Second molecule of the reagent oxidizes - at position 2 (in aldoses) or at position 1 (in ketoses) to form or respectively. The third molecule again undergoes nucleophilic addition on the newly developed carbonyl group to form osazone.

What will happen when -glucose is treated with methanolic followed by Tollens' reagent?
Detailed Solution for Test: Preparation and Reactions of Glucose - Question 6

When - glucose is treated with methanolic followed by Tollens' reagent, no characteristic colour or ppt. will be formed.
Reaction of glucose with methanolic leads to formation of methyl glucoside
(-OH group at of hemiacetal is methylated to form acetal). Acetal, is not hydrolysable by base, so it will not respond Tollen's reagent.
Note: Tollen's reagent oxidises aldehyde to carboxylate group. Tollen's reagent itself is reduced to black silver mirror. If aldehdye group is not free (such as converted to acetal), this reaction will not occur.

Among the three compounds shown below, two yield the same product on reaction with warm  The exception is:
Detailed Solution for Test: Preparation and Reactions of Glucose - Question 7

On reaction with oxidation of aldehyde and alcohol takes place which gives carboxylic acid.
But methyl do not oxidise with . Thus (a) will give same product i.e.
(Refer to Image 1 )
But (b) on oxidation give
(Refer to Image 2 ) which is different product than that given by .

-Glucose -Glucose pentaacetate
Which statement is true about glucose pentaacetate?
Detailed Solution for Test: Preparation and Reactions of Glucose - Question 8
During acetylation of -glucose, it is the of the hemiacetal that is acetylated and not the that forms the ring (cyclic structure). Since equilibrium with the open-chain aldehyde is prevented, the penta-acetate does not respond the aldehydic reactions.

The two forms of D-glucopyranose obtained from the solution of D-glucose are called
Detailed Solution for Test: Preparation and Reactions of Glucose - Question 9
Two forms of D-glucopyranose are -glucopyranose and (+)-glucopyranose. These are anomers (a pair of stereoisomers) which differ in configuration only around first carbon atom are called anomers.

Reducing saccharides among the following are
Detailed Solution for Test: Preparation and Reactions of Glucose - Question 11
Reducing saccharides are capable of acting as a reducing agent due to the presence of free aldehyde or ketone group. Ribose, maltose and lactose are reducing saccharides.

Carbohydrates are stored in plants and animals in which of the following forms respectively?
Detailed Solution for Test: Preparation and Reactions of Glucose - Question 12
Carbohydrates are stored in plants in form of starch and in animals in the form of glycogen. The starch and glycogen are broken during metabolism to release energy.

Which of the following statements are true about carbohydrates?
(i) Monosaccharides can be hydrolysed.
(ii) The two monosaccharide units obtained on hydrolysis of a disaccharide can either be same or different.
(iii) Polysaccharides are now sweet in taste.
(iv) All monosaccharides are not reducing. sugars.
Detailed Solution for Test: Preparation and Reactions of Glucose - Question 13
(i) Monosaccharides are smallest carbohydrates that cannot be hydrolysed.
So, statement (i) is not true.
(ii) Disaccharides are made up of two units of monosaccharides, so their hydrolysis will also give two monosaccharide unit that can be same or different.
e.g., Sucrose Glucose + Fructose
Maltose Glucose + Glucose
So, statement (ii) is true.
(iii) Polysaccharides are polymers of many monosaccharides and have no sweet taste.
So, statements (iii) is true.
(iv) Monosaccharides are categorised as reducing and non-reducing sugars.
So, statement (iv) is not true.

Which of the following does not reduce Benedict's solution?
Detailed Solution for Test: Preparation and Reactions of Glucose - Question 14
Sucrose, being a non-reducing sugar, does not reduce Benedict's solution. Remember that fructose has an -hydroxy ketonic group, which is also reducing group (different from ordinary ketonic group)
Test: Preparation and Reactions of Glucose - Question 15

Hydrolysis of sucrose is called
Detailed Solution for Test: Preparation and Reactions of Glucose - Question 15
Since sucrose is dextrorotatory while hydrolysis product of sucrose, having equimolar mixture of glucose and fructose, is laevorotatory. Hence the hydrolysed product of sucrose is known as invert sugar and the hydrolysis of sucrose is known as inversion.
