Question

Which of the following alcohols will give a yellow precipitate of iodoform with iodine and dilute NaOH solution?
Options
A 1-Propanol
B 2-Propanol
Correct Answer
C 1-Butanol
D 2-Methyl-2-propanol
Correct Answer

Option B is the correct answer.

Detailed Explanation

2-Propanol (isopropyl alcohol) gives a positive iodoform test (yellow precipitate of CHI3) because it has the CH3-CHOH- group. 1-Propanol and 1-butanol do not, and 2-methyl-2-propanol (tertiary) also does not.

Hint

Which alcohol has the CH3-CHOH- group for iodoform test?
