Question

Which of the following statements is incorrect for ethyl alcohol?

• A. It is neutral to litmus.
• B. It gives yellow crystalline precipitate with $I_2+dil.NaOH$
• C. It gives a product of fruity odour on reaction with $C{H}_{3}COOH$
• D. It gives turbidity spontaneously on the addition of Lucas reagent.

Answer 1

The correct option is D It gives turbidity spontaneously on the addition of Lucas reagent.

Ethyl alcohol being a primary alcohol does not show a quick reaction (turbidity) with Lucas reagent.

All alcohols, though slightly acidic are, neutral to litmus.

Ethyl alcohol oxidizes to acetaldehyde, and thus gives a positive iodoform test.

Also, it gives an ester (fruity smell) with acetic acid.

Thus, these facts explain other statements.

Option D is correct.
