Questions with solutions

Q1 — Development & Importance of Chemistry · easy · theory
In ancient India, the science of chemistry was known by which of the following names?
A. Shilpa Shastra
B. Jyotish Shastra
C. Vaastu Shastra
D. Rasayan Shastra  ✓ Correct
Solution: In ancient India chemistry was called Rasayan Shastra (also Rastantra, Ras Kriya or Rasvidya). It included metallurgy, medicine, and the manufacture of cosmetics, glass and dyes. The other "Shastras" listed deal with astronomy/architecture, not chemistry.
Q2 — Development & Importance of Chemistry · easy · theory
The drug AZT (Azidothymidine) is used in helping patients suffering from:
A. malaria
B. cancer
C. AIDS  ✓ Correct
D. tuberculosis
Solution: The chapter states that the drug AZT (Azidothymidine) is used for helping AIDS patients. Cancer therapy uses cisplatin and taxol, so AZT is specific to AIDS, not cancer or the other diseases.
Q3 — Development & Importance of Chemistry · medium · theory
Which of the following pairs of life-saving drugs is effective in cancer therapy?
A. Penicillin and taxol
B. AZT and aspirin
C. Cisplatin and taxol  ✓ Correct
D. AZT and cisplatin
Solution: Cisplatin and taxol are the two drugs mentioned as effective in cancer therapy. AZT is used for AIDS and penicillin is an antibiotic, so any pair containing them is incorrect.
Q4 — Development & Importance of Chemistry · medium · theory
The early development of chemistry (alchemy) was driven partly by the search for the Philosopher's stone (Paras), which was believed to:
A. produce unlimited mechanical energy
B. grant immortality to human beings
C. cure every known disease
D. convert baser metals like iron and copper into gold  ✓ Correct
Solution: Alchemy grew from two pursuits: the Philosopher's stone (Paras), believed to convert baser metals such as iron and copper into gold, and the 'Elixir of life', believed to grant immortality. Granting immortality was the role of the elixir, not the stone.
Q5 — Development & Importance of Chemistry · medium · theory
In ancient India, the invention of soap (using mustard oil and alkalies) is credited to:
A. Charaka
B. Nagarjuna
C. Varāhmihir
D. Chakrapani  ✓ Correct
Solution: Chakrapani discovered mercury sulphide and is also credited with inventing soap, using mustard oil and some alkalies as ingredients. Nagarjuna worked on mercury compounds, Charaka on medicine, and Varāhmihir authored the Brihat Samhita.
Q6 — Development & Importance of Chemistry · easy · theory
Which of the following are examples of 'Green House' gases whose management is a concern for chemists?
A. Oxygen and nitrogen
B. Hydrogen and chlorine
C. Helium and argon
D. Methane and carbon dioxide  ✓ Correct
Solution: The chapter cites methane (CH₄) and carbon dioxide (CO₂) as greenhouse gases. Oxygen, nitrogen and the noble gases helium and argon are not greenhouse gases in this context.
Q7 — Development & Importance of Chemistry · medium · numerical
Gypsum cement used by the Harappans contains CaCO₃. Using Ca = 40, C = 12, O = 16, the mass percentage of calcium in CaCO₃ is:
A. 12%
B. 20%
C. 40%  ✓ Correct
D. 48%
Solution: Molar mass of CaCO₃ = 40 + 12 + (3 × 16) = 100 g mol⁻¹. Mass % of Ca = (40 ÷ 100) × 100 = 40%. The 12% and 48% values are the percentages of carbon and oxygen respectively.
