Yes, one of the strongest.
hydrogen bromide is not the electrophile its bromide ion may act as the nucleophile, in alkyl halide the alkyl group may act as an electrophile.
Indicator will changes the colour according to H+ ion present in a solution. Reagent : consist of electrophile and nucleophile. It help in the attachment of nucleophile to the electrophile and electrophile to the nucleophile. Mirza
They differ in the ability of their valance electrons to be removed, ie their polarisable ability. Hard electrophile valance electrons are not easily delocalised (hardly polarisable). Soft electrophile valance electrons are easily delocalised (strongly polarisable).

This is because chlorine is an electronegative group and is pulling electrons away from benzene. This makes the ring less reactive and more positive. Then when a positive electrophile tries to attach, the benzene does not want to react.
FeCl3 being a Lewis acid accepts one chlorine with electron pair leaving the other as chloronium ion (an electrophile) which attacks on benzene ring.

In Reimer- Tieman reaction the electrophile is dichlorocarbene
The positive species which may attack on carbon or a pi bonds are electrophile as Cl+, NO2+ etc. but H+ and Positive metallic ions are not electrophile .
They differ in the ability of their valance electrons to be removed, ie their polarisable ability. Hard electrophile valance electrons are not easily delocalised (hardly polarisable). Soft electrophile valance electrons are easily delocalised (strongly polarisable).
