Mercaptans are________________?
Correct answer: D. All A., B. and C.
- A. Low boiling sulphur compounds
- B. Added in LPG cylinders to detect gas leakage by its smell
- C. Undesirable in petrol, as they reduce its octane number
- D. All A., B. and C.
Explanation
Mercaptans are low-boiling sulfur compounds with an extremely strong odour, so they are added to LPG for leak detection. They are also undesirable in petrol because they can lower its quality and octane rating, making all three statements correct.
