A
Barbituric acid - Tranquilizers

B
Aspirin - Anaesthetic

C
Ampicillin - Antibiotic

D
Phenacetin - Antipyretic

Solution

Question 3
1 / -0

The correct statements for orthoboric acid is/are:

A
it behave as a weak acid in water due to self ionisation.

B
acidity of its aqueous solution increase upon addition of ethylene glycol.

C
both (A) and (B).

D
None of these.

Solution
Question 4
1 / -0

Statement 1: Ranitidine is used to control the attack of histamine.
Statement 2: It controls the secretion of acid.

Select the correct option regarding given statements:

A
Statement 1 is true, Statement 2 is true and Statement 2 is the correct explanation of Statement 1.

B
Statement 1 is true, Statement 2 is true and Statement 2 is not the correct explanation of Statement 1.

C
Statement 1 is true, Statement 2 is false.

D
Statement 1 is false, Statement 2 is true.

Solution

Ranitidine is a histamine $$H_2-$$receptor antagonist that inhibits stomach acid production. Thus it is antihistamine and inhibits acid secretion. So both the statements are correct and R is the correct explanation of A.
Question 5
1 / -0

Which of the following is used as an anaesthetic agent?

A
$$CH_{4}$$

B
$$CO_{2}$$

C
$$N_{2}O$$

D
$$NO_{2}$$

Solution

$$ N_2O $$ is used as an anaesthetic agent in medical, dental and veterinary operatories. It has impressive safety and is excellent for providing minimal, moderate and conscious sedation.
Question 6
1 / -0

The soap molecule has a :

A
hydrophilic head and a hydrophobic tail

B
hydrophobic head and a hydrophilic tail

C
hydrophobic head and a hydrophobic tail

D
hydrophilic head and a hydrophilic tail

Solution

The basic structure of all soaps is essentially the same, consisting of a long hydrophobic (water-fearing) hydrocarbon chain tail and a hydrophilic (water-loving) anionic head.

Hence the correct option is A.
Question 7
1 / -0

A
aspirin

B
bithional

C
quinine

D
reserpine

Solution

Reserpine is an anti-psychotic and anti-hypertensive drug, extracted from the plant, Rauwolfia serpentina.
Question 8
1 / -0

The protein in blood which gives resistance to diseases is

A
Thrombin

B
Albumin

C
Immunoglobulin

D
Fibrinogen

Solution

Immunoglobulin (Ig): These are the proteins formed by the Plasma B cells for fighting against an infectious agent. Immunoglobulins are actually the Y shaped antibodies which have two heavy chains and two light chains. These antibodies recognise the antigen present upon the the surface of the foreign particle. There are 5 types of Immunoglobulins
IgG, IgA, IgM, IgE, IgD.
Thrombin: it is a protease enzyme which converts fibrinogen to fibrin in blood clotting.
Fibrinogen: It is a glycoprotein which is present in the blood in an inactive state, but upon injury it gets converted to fibrin my a cascade of enzymatic activity to form the blood clot and prevent excessive bleeding.
Albumin: It is the family of globular proteins which are water soluble.

Therefore the correct answer is C
Question 9
1 / -0

Saponification of ground nut oil yields glycerol and:

A
palmitic acid

B
sodium arachidate

C
oleic acid

D
stearic acid

Solution

Saponification of ground nut oil yields glycerol and sodium arachidate.
Question 10
1 / -0

The saponification produce:

A
soap

B
oil

C
fatty acid

D
alcohals

Solution

Saponification is a process by which triglycerides are reacted with sodium or potassium hydroxide to produce. Glycerol and fatty acid salt called soap.
