Question

In the reaction of HCl with 3-methylbut-1-ene, two products are isolated as follows. СІ HCI CI In an effort to explain the product distribution in this reaction, the following structural rearrangement has been proposed as reactive intermediates. What type of structural rearrangement is shown here? a. Two resonance forms b. A "Keto-enol tautomerism" C. A Carbocation shift d. A "1,2-Hydride shift"

Answer 1

Answer as @ A '1,92- Hydride shift. Mechanism H 1, 2 Hydride H shaft 3 # H 2° cartocation 3° Carbocation Less rtable more stable Luo ao al a As 3° carbocation is more stable than 2° Carbo- cation, 1,2 - Hydride shift so oceour
