C
Antipyretic

D
Antibiotic
Question 2
1 / -0

Copper deficiency resulting a disease which is known as

A
Skin disease

B
Menkes disease

C
Anaemia

D
Night blindness

Solution

Menkes disease is caused by mutations in genes coding for the copper-fransport protein ATP7A. So, Menkes is the disease cause by deficiency of Copper.

Detergent has a common group:

A
RONa

B
RCOONa

C
RC = CNa

D
$$ RC_6 H_4 SO_3 Na $$

Solution

The sulfonate group is joined with hydrocarbon in detergents. Detergent is a mixture of surfactants with cleaning properties in dilute solutions. The majority of alkyl sulfates are anionic detergents having long hydrocarbon chains and water-soluble ionic groups.

Hence option (D) is correct.
Question 5

An alkali salt of carboxylic acid is known as:-

A
alkaloid

B
an ester

C
a soap

D
an epoxide
