105) Which of the following statements is true when (CCl₃)₃−OH reacts with Lucas reagent?

Cloudiness appears immediately

Cloudiness appears within 10 minutes

Cloudiness will not appear at room temperature

Ketone will be formed in this reaction

Answer is:

Cloudiness will not appear at room temperature
