E1 mechanism and carbocation rearrangement 37

For the E1 dehydrohalogenation of 2-chloro-2-methylpropane in ethanol (no added strong base), the rate law is
Which of the following alkyl bromides undergoes E1 elimination (and ionisation) most readily?
In the E1 mechanism, the slowest (rate-determining) step is
2-Bromo-2-methylbutane is warmed in ethanol with no strong base present. The major alkene formed is
3-Methylbutan-2-ol is heated with concentrated H2SO4 at 440 K. The major alkene is
The rate of the E1 (ionisation) reaction of 2-chloro-2-methylpropane is expected to be highest in which solven...
Which order of the rate of E1 elimination in ethanol is correct for the tertiary halides (CH3)3C-X?
2-Bromo-3-methylbutane is heated in ethanol and reacts only by E1 (SN1 products are ignored). Assume every car...
