Chemistry - Halogen Derivative Question with Solution | TestHub

Question Explanation:

The question asks for the major product when tert-butyl chloride reacts with methoxide ion under heat, considering competing substitution and elimination pathways.

Concept Used: E2 Elimination, Steric Hindrance, Strong Base Effect

Solution:

CH₃O^- is a strong base. The substrate is tert-butyl chloride, which is highly sterically hindered.

SN² is not possible due to steric hindrance.

Under heat (Δ), E2 elimination dominates over substitution.

In E2, methoxide abstracts a β-hydrogen, leading to formation of the most substituted alkene, which is 2-

methylpropene (isobutene).

Final Answer:

Option B
