Weekly Quiz Competition

Question 1
1 / -0

What are the substances which mimic the natural chemical messengers?

A
Antibiotics

B
Antagonist

C
Agonists

D
Recepter

Solution

Agonists are the chemicals that bind to a receptor and activates the receptor to produce a biological response whereas antagonists bind to the receptor site and inhibit the natural function of drugs.
Therefore, a substance that mimics the natural chemical messengers is called agonists

Hence, the correct option is $$\text{C}$$
Question 2
1 / -0

The drug given during hypertension is?

A
Streptomycin

B
Chloroxylenol

C
Equanil

D
Aspirin

Solution

The drug given during hypertension is Equanil.
Equanil is an important tranquillizer used in depression and hypertension.
Question 3
1 / -0

Cationic surfactants is/are:

A
$$C_{17}H_{35}COONa$$

B
$$C_{17}H_{35}COOK$$

C
$$C_{17}H_{35}SO_3Na$$

D
$$C_{16}H_{33}N(CH_3)_3Cl$$

Solution

Cationic surfactant is $$C_{16}H_{33}N(CH_3)_3Cl$$. In this, the larger part (hydrocarbon) of the molecule is cation $$C_{16}H_{33}N(CH_3)_3^+$$ .
Question 4
1 / -0

Non-ionogenic surfactants are:

A

B
$$C_{17}H_{35}COONa$$

C
$$C_nH_{2n+1}(OCH_2CH_2)_x$$

D
$$all\ the\ above$$

Solution

Non ionic surfactants are $$C_nH_{2n+1}(OCH_2CH_2)_x$$. In them, the molecule is covalent and does not include cations and anions.
Question 5
1 / -0

An antipyretic is:

A
Quinine

B
Paracetamol

C
Luminal

D
Piperazine

Solution

An antipyretic reduces the body temperature.
Paracetamol is also known as acetaminophen. Chemically it is named as N-acetyl-p-aminophenol (APAP). It is used to reduce the pain and fever. Thus, it is an antipyretic.
Question 6
1 / -0

Aspirin is called:

A
pyretic

B
antiseptic

C
antibiotic

D
antipyretic

Solution

Aspirin is a medication often used to treat pain, fever, and inflammation
It inhibits the synthesis of chemicals known as prostaglandins which stimulate inflammation in the tissue and cause pain.
These drugs are effective in relieving skeletal pain such as that due to arthritis. These drugs have many other effects such as reducing fever (antipyretic).
Question 7
1 / -0

Paracetamol is a/an?

A
Antepyretic

B
Aanalgesic

C
Antimaralial

D
Both 1 and 2

Solution
Question 8
1 / -0

Detergents are prepared by the action of $${ H }_{ 2 }{ SO }_{ 4 }$$, followed by neutralization, by starting with:

A
cholesterol

B
lauryl alcohol

C
cyclohexanol

D
p-nitrophenol

Solution

Detergents are prepared by the action of $$H_2SO_4$$, followed by neutralization by starting with lauryl alcohol.

An example is $$NaLS$$ which is sodium lauryl sulphonate. Lauryl alcohol $$(C_{12}H_{26}O)$$ reacts with sulphuric acid followed by aq. $$NaOH$$ to form $$NaLS$$, $$CH_3(CH_2)_{10}OSO_3^-Na^+$$.
Question 9
1 / -0

While studying saponification reaction, a student measures the temperature of the reaction mixture and also finds its nature using blue/red litmus paper. On the basis of his observations the correct conclusion would be:

A
the reaction is exothermic and the reaction mixture is acidic

B
the reaction is endothermic and the reaction mixture is acidic

C
the reaction is exothermic and the reaction mixture is neutral

D
the reaction is exothermic and the reaction mixture is basic

E
the reaction is endothermic and the reaction mixture is basic.

Solution

To carry out saponification reaction, heat is supplied. Hence, the reaction is endothermic. Since excess NaOH is used, the reaction mixture is basic.
Question 10
1 / -0

We need a 20% aqueous solution of sodium hydroxide for the study of saponification reaction. When we open the lid of the bottle containing solid sodium hydroxide we observe it in which form?

A
Colourless transparent beads

B
Small white beads

C
White amorphous solid

D
Fine white powder

E
White pellets/ flakes

Solution

Sodium hydroxide is generally available in the form of white pellets/ flakes. Note: Sodium hydroxide is highly hygroscopic. Hence, it should be prevented from moisture.
