Why the 1St Position of Naphthalene Is More Reactive Than 2Nd Position Explain Giving Mechanism?

Substitution usually occurs more readily at the 1 position than at the 2 position because the intermediate for 1-substitution is more stable than that for 2-substitution. The reason is that the most favorable resonance structures for either intermediate are those that have one fully aromatic ring.

Why alpha position of naphthalene is more reactive than beta position?

The alpha position is more prone to reaction position in naphthalene because the intermediate formed becomes more stable due to more diffusion of charges through the adjacent pie electrons. Thus resonance do have its role to play in reactivity of alpha position.

Which position in naphthalene is more reactive?

Explanation: In the electrophilic substitution, position 1 in naphthalene is more reactive that the position 2 because the carbocation formed by the attack of electrophile at position 1 is more stable than position 2 because of the resonance since it has 4 contributing structures.
