CH₃
CH₃

(d) CH₃CH₂ —CH —OH
|
CH₃

Answer 1

The tertiary alcohol will most readily undergo the reaction.

Explanation:

• The reaction between the alcohol and concentrated HCl yields alkyl halide and water.

• This reaction follows the SN1 mechanism.

• So the carboncation formation is necessary.

• As the hydrogen from HCl protonates the hydroxyl group of the alcohol, the water leaves forming the carbocation.

• The stability of the carboncation is in the order of 3°>2°>1°.

• So,the most stable carboncation will be formed with the tertiary alcohol.

• This will lead to the formation of RX.
