Question

Which one among the following compounds will most readily be dehydrated under acidic condition? 

• A. Option a
• B. Option b
• C. Option c
• D. Option d

Hint:

Acidic dehydration trend:
\[ 3^\circ > 2^\circ > 1^\circ \]
More stable carbocation \( \Rightarrow \) faster elimination.

Answer 1

The Correct Option is D

Concept:
Ease of dehydration depends on:

• Stability of carbocation formed
• Tertiary > Secondary > Primary

Step 1: Evaluate options

• Primary alcohol (A): difficult dehydration
• Alpha or beta hydroxy ketones: less favorable
• Tertiary alcohol (D): forms stable 3° carbocation

Conclusion:
Tertiary alcohol dehydrates most easily.
