Answer 1

Greater the stability of carbocation formed, greater is the reactivity. Benzyl carbocation is resonance stabilized.

$∴ t e r t i a r y > b e n z y l > s e c o n d a r y > p r i m a r y$

Option B is correct.

Answer 2

Greater the stability of carbocation formed, greater is the reactivity. Benzyl carbocation is resonance stabilized.

∴ t e r t i a r y > b e n z y l > s e c o n d a r y > p r i m a r y

Option B is correct.

The order of reactivity of alcohols towards hydrogen halide is :

$b e n z y l > 3^{0} > 2^{0} > 1^{0}$

$3^{0} > b e n z y l > 2^{0} > 1^{0}$

$3^{0} > 2^{0} > 1^{0} > b e n z y l$

$3^{0} > 2^{0} > b e n z y l > 1^{0}$

Greater the stability of carbocation formed, greater is the reactivity. Benzyl carbocation is resonance stabilized.

$∴ t e r t i a r y > b e n z y l > s e c o n d a r y > p r i m a r y$

Option B is correct.

The order of reactivity of dehydration of alcohol is :

The order of reactivity of alcohols towards hydrogen halide is :

benzyl>30>20>10

30>benzyl>20>10

30>20>10>benzyl

30>20>benzyl>10

Greater the stability of carbocation formed, greater is the reactivity. Benzyl carbocation is resonance stabilized. ∴ tertiary>benzyl>secondary>primary Option B is correct.

$3^{0} > 2^{0} > 1^{0} > b e n z y l$

$3^{0} > 2^{0} > b e n z y l > 1^{0}$

Greater the stability of carbocation formed, greater is the reactivity. Benzyl carbocation is resonance stabilized.

$∴ t e r t i a r y > b e n z y l > s e c o n d a r y > p r i m a r y$

Option B is correct.
