Which among the following forms minimum boiling azeotropes?
(i) Heptane + Octane
(ii) Water + Nitric acid
(iii) Ethanol + Water
(iv) Acetone + Carbon disulfide
- A (i), (ii), (iv)
- B (i), (ii) only
- C (iii), (iv)
- D (iv) only
Answer & Solution
Correct Answer
(C) (iii), (iv)
Step-by-step Solution
Detailed explanation
Minimum boiling azeotropes are formed by solutions showing large positive deviation from Raoult's law, where A-B interactions are weaker than A-A and B-B interactions. (i) Heptane + Octane: Both are similar non-polar alkanes, forming a nearly ideal solution. No azeotrope formed.…
