Explanation:

The reaction between the tert-butanol and the hydrochloric acid is depicted in the following reaction (2 steps):

In this reaction, the first step is an acid-base reaction where, the lone pair on oxygen atom of the alcohol will attack the hydrogen of the acid to form the leaving group #OH_2^+#.

Since #H_2O# is a weaker base than #Cl^-#, in a second step, the #Cl^-# will attack the carbon atom attached to #OH_2^+# which will leave to give water and the tert-butyl chloride.

The #beta# elimination product can also form:
