(a) Write the equations for the steps involved in SN^(1) mechanism for the conversion of tert-butyl bromide totert-butyl alcohol. |

Answer» Solution :(a)The reaction between tert-BUTYL bromide and hydroxide ion gives tert-butyl alcohol. The rate of reaction depends only on the concentration of tert-butyl bromide. HENCE it is a nucleophilic first order substitution reaction. `H_(3)C_underset(CH_(3))underset(|)OVERSET(CH_(3))overset(|)(C)-Br)+OH^(-) to H_(3)C-underset(CH_(3))underset(|)overset(CH_(3))overset(|)(C)-OH+Br^(-)` Mechanism: Step 1: Polarised C-Br undergoes cleavage to produce planar carbocation.  Step 2: The carbocation is then attacked by NUCLEOPHILE `(OH^(-))` on either side to form tert butyl alcohol.  (b) When chlorobenzene is heated with acetyl chloride, 2-chloroacetophenone and 4-chloroacetophenone is obtained.  (c) Equimolar mixture of d and l isomers. |
