Select the minimum number of carbon atoms, a molecule must possess so as to be regarded as a higher alkane.
Correct answer: D. 18
- A. 15
- B. 16
- C. 17
- D. 18
Explanation
The correct answer is Option D:18. A molecule with 18 carbon atoms or more is regarded as a higher alkane, such as waxes and solids. Options A, B, and C are incorrect as they do not meet the minimum number of carbon atoms required to be classified as a higher alkane.
