Chemistry - Halogen Derivative Question with Solution | TestHub
Which of the following compounds will give E1 reaction?
Options:(select one or more)
Answer:
Solution:
Question Explanation:
The question asks to identify which of the given compounds can undergo an E1 (unimolecular elimination) reaction.
Concept:
This question is based on the E1 reaction mechanism and carbocation stability.
Solution:
An E1 reaction proceeds in two steps, with the formation of a carbocation intermediate as the rate determining step. Therefore, the feasibility of an E1 reaction primarily depends on the stability of the carbocation formed after the leaving group departs.
Options (1, 2 & 3) form a resonance-stabilized carbocation .
Option (4) forms a tertiary (3°) carbocation , which is stabilized by hyperconjugation and the inductive effect .
Since resonance-stabilized carbocations and tertiary carbocations are highly stable, all the given substrates readily undergo the E1 reaction.
Final Answer: Options (1), (2), (3), and (4) .
