CUET Chemistry Mock Test

CUET Chemistry Question No: 1

Carbohydrate that cannot be hydrolysed further to give simpler unit of polyhydroxy aldehyde or ketone is called

Option A : monosaccharide

Option B : oligosaccharide

Option C : polysaccharide

Option D : sucrose

Show/Hide Answer Key

Option A: monosaccharide

Due to the presence of trivalent N-atom and unshared pair of electrons in amines, hybridisation and geometry become sp3 and pyramidal respectively.

CUET Exam Chemistry Question No: 2

Name the reagent and condition required for carrying out the following reaction.

Option A : HF, Δ

Option B : HCI, Δ

Option C : HBr, Δ

Option D : HI, Δ

Show/Hide Answer Key

Option D: HI, Δ

The reagent for the given reaction is HI. On prolonged heating with HI, glucose forms hexane, suggesting that all 6C-atoms are linked in a straight chain.

CUET Domain Subject Chemistry Question No: 4

Invert sugar is a mixture of

Option A : D-glucose + D-fructose

Option B : L-glucose + D-fructose

Option C : L-glucose + D-glucose

Option D : L-glucose + L-glucose

Show/Hide Answer Key

Option A: D-glucose + D-fructose

Invert sugar is a mixture of D-glucose and D-fructose. Sucrose is also known as invert sugar. Solution of sucrose is dextrorotatory. When sucrose is hydrolysed it forms equimolar quantity of D-glucose and D-fructose. The solution of formed products is found to be laevorotatory. This change in optical properties of sucrose is called inversion of cane sugar. The equimolar product is formed, i.e. D-glucose and D-fructose is called invert sugar.

CUET BSc Chemistry Question No: 5

Option A : Sucrose

Option B : Maltose

Option C : Lactose

Option D : Talose

Show/Hide Answer Key

Option C: Lactose

The given disaccharide is lactose. In this structure, the linkage is between C1 of galactose and C4 of glucose.

CUET Entrance Exam Chemistry Question No: 6

Which of the following is known as animal starch?

Option A : Amylose

Option B : Amylopectin

Option C : Glycogen

Option D : Cellulose

Show/Hide Answer Key

Option C: Glycogen

Glycogen is also known as animal starch because its structure is similar to amylopectin and is rather more highly branched. The carbohydrates get stored in animal body as glycogen.
