Question

Which of the following alcohols will yield the corresponding alkyl chloride on reaction with concentrated HCl at room temperature?

Answer 1

d)

bzc tertiary alcohols are more reactive than any others

Answer 2

Answer:

Option D

Explanation:

All the alcohols such as the primary,secondary and tertiary alcohols reacts with Lucas reagent ( zncl2) forming the corresponding halides. While primary alcohol requires much heating, secondary requires less heating than the primary. Tertiary readily reacts in room temperature since it forms a 3 degree carbocation which is much stable.

Thus, since tertiary carbocation is most stable. so the tertiary alcohols are most reactive towards the cone. HCL. Thus, the reaction can be conducted at room temperature only, while both the primary and secondary alcohols require the presence of a catalyst Zncl2.

Hence, option d is correct.
