Answer

  Column I   Column II
(i) Chloramphenicol (c) Typhoid fever
(ii) Thyroxine (d) Goiter
(iii) Chloroquine (a) Malaria
(iv) Chloroform (b) Anaesthetic
    (e) Blood substituent

Explanation:

  1. Chloramphenicol is a broad spectrum antibiotic. It is used in the treatment of typhoid fever.
  2. Thyroxine is a hormone secreted by thyroid gland. Excessive secretion of thyroxine in the body is known as hyperthyroidism. Most patient with hyperthyroidism have an enlarged thyroid gland i.e., goiter.
  3. Chloroquine, prevents the development of malaria parasite plasmodium vivax in the blood.
  4. IUPAC name of chloroform is trichloromethane with formula CHCl3. It is a colourless compound. Volatile, sweet-smelling liquid. Its vapours depresses the central nervous system and used as an anaesthetic.
