Weekly Quiz Competition

Question 1
1 / -0

The correct match between items of List- I and List- II is:
List I List II
(A) Phenelzine (P) Pyrimidine
(B) Chloroxylenol (Q) Furan
(C) Uracil (R) Hydrazine
(D) Rantitidine (S) Phenol

A
(A)- (S); (B)- (R); (C)- (P); (D)-(Q)

B
(A)- (R); (B)- (S); (C)- (P); (D)-(Q)

C
(A)- (R); (B)- (S); (C)- (Q); (D)-(P)

D
(A)- (S); (B)- (R); (C)- (Q); (D)-(P)

Solution

Phenelzine contain hydrazine, choloroxylenol contains phenol, uracil contains pyrimidine ring and rantitidine contains furan ring. Hence, the option B is correct.
Question 2
1 / -0

Noradrenaline is a/an:

A
neurotransmitter

B
antidepressant

C
antihistamine

D
antacid

Solution

Noradrenaline is a neurotransmitter and it belongs to catecholamine family that functions in brain and body as a hormone and neuro transmitter.
Question 3
1 / -0

Which artificial sweetener contains chlorine?

A
Sucralose

B
Alitame

C
Saccharin

D
Aspartame

Solution

Sucralose is the artificial sweetener which contains chlorine.
It is trichloro derivative of sucrose. It is $$600$$ times sweeter than the cane sugar.
Question 4
1 / -0

The reason for "drug induced poisoning" is:

A
binding at the allosteric sites of the enzyme

B
binding irreversibly to the active site of the enzyme

C
binding reversibly at the active site of the enzyme

D
bringing conformational change in the binding site of the enzyme

Solution

The reason for "drug induced poisoning" is the binding of drug, irreversibly, to the active site of the enzyme. If this happens, then body degenerates the enzyme and releases a new enzyme.
Question 5
1 / -0

Which of the following is an anionic detergent?

A
Sodium lauryl sulphate

B
Cetyltrimethyl ammonium bromide

C
Glyceryl oleate

D
Sodium stearate

Solution

Sodium lauryl sulphate is an anionic detergent. It has anion at the soluble end of the chain.

It is a sodium salt of the sulfonated long chain of lauryl alcohol.

Hence, option A is correct.
Question 6
1 / -0

Which one of the following is used as antihistamine?

A
Norethindrone

B
Chloranphenicol

C
Diphenhydramine

D
Omeprazole

Solution

Diphenhydramine is an antihistamine used to relieve symptoms of allergy, hay fever, and the common cold. It is used by mouth, injection into a vein, and injection into a muscle.

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

Which of the following compounds is not an antacid?

A
Aluminium hydroxide

B
Cimetidine

C
Phenelzine

D
Ranitidine

Solution

Phenelzine (also known as Nardil) is an antidepressant drug (also known as tranquillizer).

Aluminium hydroxide, Cimetidine and Ranitidine are antacids.

Hence, option C is correct.
Question 8
1 / -0

Which of the following is a cationic detergent?

A
Sodium stearate

B
Cetyltrimethyl ammonium bromide

C
Sodium dodecylbenzene sulphonate

D
Sodium lauryl sulphate

Solution

Cationic detergents are quaternary ammonium salts of amines with acetate, chlorides, or Bromides as anions.

Cations are long-chain hydrocarbons having a positive charge on N atom. Eg: Cetyl trimethyl ammonium bromide

$$C_{19}H_{42}N^{+}Br^{-}$$ (cationic detergent)

Synthetic detergents
Question 9
1 / -0

The method used to remove temporary hardness of water is :

A
Calgon's method

B
Clark's method

C
Ion-exchange method

D
Synthetic resins method

Solution

Clark's method is used to remove the temporary hardness of water, in which bicarbonates of calcium and magnesium are reacted with slaked lime $$Ca(OH)_2$$.

$$Ca(HCO_3)_2+Ca(OH)_2\rightarrow 2CaCO_3\downarrow+2H_2O$$
$$Mg(HCO_3)_2+2Ca(OH)_2\rightarrow2CaCO_3\downarrow+Mg(OH)_2\downarrow+2H_2O$$

Hence, option B is correct.
Question 10
1 / -0

Which of the following is an analgesic?

A
Novalgin

B
Penicillin

C
Streptomycin

D
Chloromycetin
