Weekly Quiz Competition

Question 1
1 / -0

Which of the following is the structure of Aspirin?

A

B

C

D

Solution

The structure of aspirin is shown in the figure.
Question 2
1 / -0

Aspirin has a degree of unsaturation of:

A
$$4$$

B
$$5$$

C
$$6$$

D
$$7$$

Solution

Aspirin has $$5$$ $$\pi$$-bonds and one ring as evident from the figure above. So, it has a degree of unsaturation of $$6$$.
Question 3
1 / -0

Substances which are used to bring down the temperature in high fever condition, are called:

A
antiseptics

B
pyretics

C
antibiotics

D
antipyretics

Solution

An Antipyretics is a type of medication that prevents or reduces fever by lowering body temperature from a raised state.
Question 4
1 / -0

Which one of the following is employed as antihistamine?

A
Diphenyl hydramine

B
Norethindrone

C
Omeprazole

D
Chloramphenicol
Solution
Correct Option : $$A$$
Explanation:
- Antihistamine: These drugs block receptors of histamine and thus help to control inflammation and allergic reactions.
  Example: Diphenyl hydramine, Chlorphenamine, etc.
- Birth control pills: These drugs contain steroid hormones like progesterone which prevent ovulation, thus helping in birth control. They may also be used to treat a variety of gynecological disorders.
  Example: Norethisterone, etc.
- Antacids: This class of drug helps to reduce acid produced in the stomach, thus preventing damage to the lining of the stomach.
  Example: Omeprazole, etc.
- Antibiotics: These drugs are used to kill disease-causing agents called pathogens that enter the human body, thus, they are prolife with respect to humans.
  Example: Chloramphenicol, Streptomycin, etc.
Hence, option A is the correct answer.
Question 5
1 / -0

Which of the following is not an antihistamine?

A
Brompheniramine

B
Terfenadine

C
Iproniazid

D
Ranitidine

Solution

Iproniazid (Marslid, Rivivol, Euphozid, Iprazid, Ipronid, Ipronin) is a non-selective, irreversible monoamine oxidase inhibitor (MAOI) of the hydrazine class. It is a xenobiotic that was originally designed to treat tuberculosis, but was later most prominently used as an antidepressany drug.
Question 6
1 / -0

The stiochiometry of the following reaction is:

$$K_{2}S_{2}O_{8}(aq) + 2KI(aq)\rightarrow 2K_{2}SO_{4}(aq) + I_{2}(aq)$$

A
$$2 : 1$$

B
$$1 : 2$$

C
$$2 : 2$$

D
$$1 : 3$$

Solution

Stoichiometry of a reaction is given on the basis of the stoichiometric ratio of reactants.

1 mole of $$K_2S_2O_8$$ reacts with 2 moles $$KI$$. So, for the given reaction, it is $$ 1:2$$.

Hence, option B is correct.
Question 7
1 / -0

Antiseptics and disinfectants either kill or prevent growth of microorganisms. Which of the following statements is not true?

A
Chlorine and Iodine are used as strong disinfectants

B
Dilute solutions of Boric acid and Hydrogen Peroxide are strong antiseptics

C
Disinfectants harm the living tissues

D
A 0.2% solution of phenol is an antiseptic while 1% solution acts as a disinfectant

Solution

Antiseptic and disinfectants both either kill or prevent the growth of microorganisms. The main point of difference between these two is that the former (antiseptic) are used for living beings whereas disinfectants are not safe for living tissues.
A substance like phenol in its lower concentration (0.2%) behaves as antiseptic whereas in higher concentration (1%) as a disinfectant.
Chlorine and iodine are strong disinfectants whereas dilute solutions of boric acid and hydrogen peroxide are mild antiseptic.
Question 8
1 / -0

Which one of the following drugs prevents the interaction of histamine with its receptor?

A
Antihistamines

B
Analgesics

C
Antibiotics

D
Disinfectants

Solution

Antihistamines are drugs which treat allergic rhinitis and other allergies. Antihistamines can give relief when a person has nasal congestion, sneezing, or hives because of pollen, dust mites, or animal allergy. Typically people take antihistamines as an inexpensive, generic, over-the-counter drug with few side effects. As an alternative to taking an antihistamine, people who suffer from allergies can instead avoid the substance which irritates them. However, this is not always possible as some substances, such pollen, are carried in the air, thus making allergic reaction caused by them generally unavoidable.
Question 9
1 / -0

Which one of the following is employed as Antihistamine?

A
Omeprazole

B
Chloramphenicol

C
Diphenhydramine

D
Norethindrone
Question 10
1 / -0

Which of the following soap/detergent has least biodegradability?

A
$$CH_{3}-(CH_{2})_{11} - OSO_{2}Na$$

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

C

D

Solution

Alkyl benzenesulphonates, derived from branch chain alkanes, have much lower biodegradability due to the large size of molecules and branching while polymerisation. Hence, $$C$$ is the correct option.
