Question

consider compound A = 2 chloro 2 methylbutane, B= 2 chloro butane, C = 2 chloropropane, which of the company will readily undergo dehydrochlorination

Answer 1

The answer is compound A.

If the mechanism of elimination is E1 then the reactivity of dehydrohalogenation is dependent on stability of carbocation. The more stable the carbocation the more readily it undergoes the reaction. The compound A will produce tertiary carbocation, the most stable one.
