Show Answer
Answer:
Correct Answer: 27.
Solution:
- PLAN This problem is based on structure and nomenclature of organic compound.
Draw structure of each compound and write IUPAC name of the given compound.
Match the molecular formula of given compound with molecular formula of compound given in choices.
The combination of names for possible isomeric alcohols with molecular formula
| Formula | Names |
|---|---|
| n-butyl alcohol / n-butanol / butan-1-ol |
|
| Iso-butyl alcohol / 2-methyl propan-1-ol |
|
| Secondary butyl alcohol / butan-2-ol |
|
| Tertiary butyl alcohol / tert butanol / 2-methyl propan-2-ol |
|
Hence, choices (a), (c) and (d) are correct.
