Correct answer: C. Both (a) & (b)
- A. C16
- B. C18
- C. Both (a) & (b)
- D. C10
Explanation
C16 and C18 hydrocarbons have high molecular masses and very low volatility, so they are not normally present as freely circulating atmospheric gases. Lower-carbon hydrocarbons are much more likely to occur in the atmosphere in gaseous form.
