NEET · Chemistry · STD 12 - 7. Alcohol, phenol and ethers
Number of isomeric alcohols of molecular formula \(C_6H_{14}O\) which give positive iodoform test is
- A \(3\)
- B \(4\)
- C \(5\)
- D \(2\)
Answer & Solution
Correct Answer
(B) \(4\)
Step-by-step Solution
Detailed explanation
The iodoform test is positive for alcohols with formula \(\mathrm{R}-\mathrm{CHOH}-\mathrm{CH}_{3}\). Among \(\mathrm{C}_{6} \mathrm{H}_{14} \mathrm{O}\) isomers, the ones with posith positive iodoform test are: \(I.\) \(\mathrm{CH}_{3}-\mathrm{CH}_{2}-\mathrm{CH}_{2}-\mathrm{CH}_{2}-\mathrm{CHOH}-\mathrm{CH}_{3}\) -\(2-\)Hexanol
