MCQ
IUPAC name of the compound CH3−CH(CH2CH3)−CH2−CH(OH)−CH3 is:
- A4-Ethyl-2-pentanol
- B4-Methyl-2-hexanol
- C2-Ethyl-2-pentanol
- D3-Ethyl-2-hexanol
✓
Answer
- 4-Methyl-2-hexanol
Explanation:
Longest carbon chain has 6 atoms. We number from right hand side as alcohol group at C-2 gets least number in this case and suffix used for alcohol is "-ol". Methyl group is present at C-4 position.
Thus, IUPAC name is 4-Methyl-2-hexanol.
