Predict in which of the following cases, the reaction with Lucas reagent will be immediate, slow or will not take place at all at room temperature?                                      (a) (b) (c)

Answer:

                (a) Structural formula represents a secondary alcohol. Therefore, it will give white turbidity with Lucas reagent after some time i.e. the reaction is slow. (b) Structural formula is of a primary alcohol which gives white turbidity with Lucas reagent only upon heating. (c) Structural formula is of a tertiary alcohol and it will give white turbidity with Lucas reagent immediately.
