Lucas test is used for the determination of

Options

  1. Aaldehydes
  2. Bphenols
  3. Ccarboxylic acid
  4. Dalcohols

Correct answer

D. alcohols

Step-by-step solution

Lucas test is used to distinguish alcohols. Lucas reagent is a solution of anhydrous zinc chloride in concentrated HCl . Lucas reagent converts alcohols to alkyl chlorides. Tertiary alcohols give immediate reaction with Lucas reagent, secondary alcohols give reaction within five minutes, while primary alcohol do not give reaction with it.
