Solution
The correct option is B 2-Methyl-2-butanol
Primary, Secondary, and Tertiary alcohols react with the Lucas reagent to form the chloroalkane at different rates.
The solution remains colourless unless it is subjected to heat in case of primary alcohol. The solution forms no turbidity.
The solution turns turbid and forms an oily layer in 5 to 10 minutes in case of secondary alcohol.
The solution turns turbid instantly and forms an oily layer immediately in case of tertiary alcohol.
2-Methyl-2-butanol will give immediate turbidity when reacted with Lucas reagent because it is tertiary 3o alcohol.
