Question

The correct order of acid catalysed dehydration of alcohols is: (A) 1°>2°>3° (B) 3°>2°>1° (C) 2°>1°>3° (D) 1°>3°>2°

Tardigrade Admin · Accepted Answer

Dehydration involves the formation of carbocation, intermediates. More the stability of carbocation formed, more is the ease of dehydration. ∴ Stability of carbocation: 3°>2°>1°

Q. The correct order of acid catalysed dehydration of alcohols is:

$1^{\circ} > 2^{\circ} > 3^{\circ}$

$3^{\circ} > 2^{\circ} > 1^{\circ}$

$2^{\circ} > 1^{\circ} > 3^{\circ}$

$1^{\circ} > 3^{\circ} > 2^{\circ}$

Dehydration involves the formation of carbocation, intermediates. More the stability of carbocation formed, more is the ease of dehydration.

$∴$ Stability of carbocation $: 3^{\circ} > 2^{\circ} > 1^{\circ}$

Q. The correct order of acid catalysed dehydration of alcohols is:

1∘>2∘>3∘

3∘>2∘>1∘

2∘>1∘>3∘

1∘>3∘>2∘

Dehydration involves the formation of carbocation, intermediates. More the stability of carbocation formed, more is the ease of dehydration. ∴ Stability of carbocation :3∘>2∘>1∘

$1^{\circ} > 2^{\circ} > 3^{\circ}$

$3^{\circ} > 2^{\circ} > 1^{\circ}$

$2^{\circ} > 1^{\circ} > 3^{\circ}$

$1^{\circ} > 3^{\circ} > 2^{\circ}$

Dehydration involves the formation of carbocation, intermediates. More the stability of carbocation formed, more is the ease of dehydration.

$∴$ Stability of carbocation $: 3^{\circ} > 2^{\circ} > 1^{\circ}$
