Weekly Quiz Competition

Question 1
1 / -0

Phenelzine is used as an:

A
analgesic

B
antiseptic

C
antipyretic

D
antidepressant

Solution

Phenelzine is a drug which belongs to a class of antidepressants called monoamine oxidase inhibitors (MAOIs), used to treat depression.

This medication treats depression by restoring the balance of certain natural substances (neurotransmitters) in the brain. Phenelzine can improve your mood and feelings of well-being.

Hence, option D is correct.
Question 2
1 / -0

Antacids are used:

A
to produce acid in the stomach

B
to produce water in the stomach

C
to neutralise the excess base in the stomach

D
to neutralise the excess acid in the stomach

Solution

Antacid is a substance which neutralizes stomach acidity and in turn, relieves heartburn, indigestion or stomach upset. Antacids contain alkaline ions which neutralizes the acids in the stomach i.e gastric acids, reducing the damage and relieving pain.
Question 3
1 / -0

The yellow in egg yolk is a coloring caused by:

A
An FD & C dye added to the egg.

B
A carotenoid

C
An anthocyanin

D
Natural means..the fat is just yellow.

Solution

The yellow in egg yolk is a coloring due to the presence of carotenoid.
Hence option B is correct.
Question 4
1 / -0

The common raw material used in the preparation of soap and detergent is:

A
sulphuric acid

B
sodium hydroxide

C
stearic acid

D
long chain hydrocarbons

Solution

Soaps are water-soluble sodium or potassium salts of fatty acids like stearic acid. [e.g. Sodium Stearate]. Soaps are made from fats and oils, or their fatty acids, by treating them chemically with a strong alkali.

Detergents are made up of concentrated acids which react with alkalis to form salts. These salts contain long-chain molecules with an ionic sulphonate group. Hence, both require a strong alkali like NaOH.

Hence, option B is correct.
Question 5
1 / -0

Antispasmodics are a group (class) of medicines that can help to control some symptoms that arise from _____________ part of the human body especially.

A
intestine

B
lungs

C
kidney

D
head

Solution

Antispasmodics are a group (class) of medicines that can help to control some symptoms that arise from the gut (intestines) - in particular, gut spasm. One type of antispasmodics is used for smooth muscle relaxation, especially in tubular organs of the gastrointestinal tract. The effect is to prevent spasms of the stomach.
Hence option A is correct
Question 6
1 / -0

Reactive dyes utilize a _________ attached to a substituent that is capable of directly reacting with the fibre substrate.

A
chromophore

B
auxochrome

C
chlorophyll

D
none of the above

Solution

Reactive dyes utilize a chromophore attached to a substituent that is capable of directly reacting with the fiber substrate. The covalent bonds that attach the reactive dye to natural fibers make them among the most permanent of dyes. 'Cold' reactive dyes, such as Procion MX, Cibacron F, and Drimarene K, are very easy to use because the dye can be applied at room temperature. Reactive dyes are by far the best choice for dyeing cotton and other cellulose fibers at home or in the art studio.
Hence option $$A$$ is correct.
Question 7
1 / -0

Azoic dyeing is a technique in which an insoluble ..................... compound dye is produced directly onto the fiber.

A
azo

B
sulphur containing

C
carbonyl

D
carboxylic acid

Solution

Azoic dyeing is a technique in which an insoluble Azo dye is produced directly onto or within the fiber. This is achieved by treating a fiber with both diazo and coupling components.
With suitable adjustment of dyebath conditions, the two components react
to produce the required insoluble azo dye. This technique of dyeing is unique, in that the final color is controlled by the choice of the diazoic and coupling components.
Hence option A is correct.
Question 8
1 / -0

Cisplatin compound is used in the treatment of:

A
malaria

B
cancer

C
AIDS

D
yellow fever

Solution

Cisplatin compound is used in the treatment of cancer. It is represented as $$\displaystyle [PtCl_2(NH_3)_2]$$. Its IUPAC name is dichloro diamine platinum (IV).

Two chlorine atoms are cis (adjacent) to each other. Similarly, two amine ligands are cis (adjacent) to each other. It has a square planar geometry.

Hence, option B is correct.
Question 9
1 / -0

While studying the saponification reaction, what do you observe when you mix an equal amount of colourless vegetable oil and 20% aqueous solution of $$NaOH$$ in a beaker?

A
The colour of the mixture has become dark brown

B
A brisk effervescence is taking place in the beaker

C
The outer surface of the beaker has become hot

D
The outer surface of the beaker has become cold

Solution

While studying the saponification reaction the outer surface of the beaker becomes hot as the saponification reaction is exothermic in nature.
Question 10
1 / -0

Which of the following functional groups constitutes the formation of detergent?

A
$$SO_3Na$$

B
$$COONa$$

C
$$COOH$$

D
$$OH$$

Solution

The functional group $$SO_3Na$$ constitutes the formation of detergent.

$$CH_3-(CH_2)_{11} - \underset{O}{\underset{||}{\overset{O}{\overset{||}{S}}}} - OH+ NaOH \to CH_3-(CH_2)_{11} - \underset{O}{\underset{||}{\overset{O}{\overset{||}{S}}}} - O^-Na^++ H_2O$$
dodecyl sulphonic acid sodium dodecyl sulphate

Hence, option A is correct.
