What? there isn’t a question here
It has two elements.
Magnesium shows +2and Cl shows -1.
Refraction is the phenomenon of change in the speed of light when the light when passes from the medium of one optical density to a medium of another optical density. The light rays also show a bending when passing through the interface of such a medium.
<h3>What causes wave refraction?</h3>
Refraction is the bending of waves due to a change in speed as they travel through different media. Waves may accelerate or decelerate when they go obliquely from one medium to another. The waves will bend more dramatically as their speed changes.
<h3>What characteristics does a wave have?</h3>
The following characteristics of waves:
- Refraction is the bending of waves as they move from one medium to another due to a change in their speed.
- Waves may speed up or slow down as they transition from one medium to another at an angle.

Answer:
The electrophile is the hydroxide free radical
Explanation:
The hydroxylation of benzene and benzene derivatives using hydrogen peroxide proceeds in the presence of an acidic catalyst. The electrophile in this reaction is the hydroxyl free radical generated in an initial step of the reaction.
This is actually a free radical reaction. The hydroxyl radical previously generated reacts with the benzene ring to yield a radical that undergoes further rearrangement to yield the product phenol. The intermediate, shown as part of this reaction mechanism (refer to image attached) is a specie in which the odd electron is delocalized over the entire benzene ring. Loss of a proton completes the reaction mechanism yielding the corresponding phenol.
