Question

Resonance effect involves :
(1) Delocalization of 1 -electrons along a conjugated system
(2) Delocalization of lone pair along a conjugated system
(3) Delocalization of negative charge along a conjugated system
(4) All are correct​

Answer 1

Answer:

(4) option

Explanation:

all are correct

Answer 2

(There is an error in the question. It should be $\[\pi \]$-electrons instead of 1-electrons.)

The resonance effect involves the Delocalization of $\[\pi \]$-electrons along a conjugated system, the delocalization of lone pair along a conjugated system and the delocalization of negative charge along a conjugated system. Thus, the correct option is (4) All are correct​.

Explanation:

• Resonance is a method of representing the delocalised electrons within a molecule that cannot be represented by a single structure.
• In resonance, the delocalisation of $\[\pi \]$-electrons along the conjugated system takes place.
• It also involves the delocalization of lone pair of electrons along a conjugated system and the delocalization of negative charge along a conjugated system.
• Therefore, all statements are correct.
