Expert Answer
CH3-CH2-C(CH3)2Cl + OH-? CH3-CH2-C(CH3)2OH + Cl-
mecanism : CH3-CH2-C(CH3)2Cl 
CH3-CH2-(CH3)2-C+ + Cl- slow
CH3-CH2-(CH3)2-C+ + Cl- slow CH3-CH2-(CH3)2-C+ + OH- ? CH3-CH2-C(CH3)2OH fast step
the reaction occurs by SN1 mecanism .It occurs in two steps as shown above .In step one C-halogen bond undergoes slow cleavage.It is a reversible step
The carbocation formed in first step is very reactive it readily reacts with a nucleophile , OH-
obtained from alcoholic KOH and hence forms the alcohol.
