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.
NO2+ is.
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
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 .
Yes, one of the strongest.
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).
singlet
To form an active electrophile NO2+
Ch3CN
No, alkenes have pi bond so they are nucleophilic and may be attacked by an electrophile.
O is act as electrophile ie basic & more electronegative
