Answer #1

According to your specify b and e.

Reaction b is prefer Elimination of a proton(H+)

Reaction e is prefer Elimination of a proton(H+) via rearangement of Carbocation:

And Rearangement reaction are occurs to give most stable major product.

Both prefer E1 mechanism with substrate and weak base.

On image Show the reaction meachanism of b ans e.

t20 4x - Hydrogen 34 - Hydrogen (Major product) - H304 3o-Comboccation 1,2 Hydride shift Rearrangement 2²-Carbocation! H₂6 +
