23. Answer BOTH parts of this question. (a) Which two pieces of experimental evidence can be used to demonstrate that a chiral secondary alkyl halide (R-X) reacts with water to form a secondary alcohol (ROH) via an SN1 reaction? Give clear explanations for both cases. There is no need to draw diagrams. (4 marks) (b) When 2-methylpropene reacts with HBr under ionic conditions, the major product is 2-bromo-2-methylpropane: HyC HBr C=CH2 (CH3)2CBr H₂Ć Using curly arrows, show the mechanism for this reaction, explaining why the major product is 2-bromo-2- methylpropane rather than an isomer of it.
