Is Br2 an electrophile or nucleophile?
Br2 is an electrophile. When we are taking conditions of free radical like in the presence of sunlight, CCl4, Peroxide. In that case homolytic cleavage will take place and Br free radicals will be produced which are electron deficient and hence electrophile.
What is the nature of Br2?
Elemental bromine is very reactive and thus does not occur free in nature, but in colourless soluble crystalline mineral halide salts, analogous to table salt….

Is electrophilic or nucleophilic?
Difference between Electrophile and Nucleophile
| The difference between Electrophile and Nucleophile is listed below. | |
|---|---|
| They undergo electrophilic addition and electrophilic substitution reactions | They undergo nucleophilic addition and nucleophilic substitution reactions |
| Electron-deficient | Electron-rich |
Is NH2 a nucleophile?
A negatively charge compound or a compound with lone pair of electron is a nucleophile. Therefore NH2– is a nucleophile. And a nucleophile can never react like a electrophile as it doesn’t need to accept electrons.

Can bromine be a nucleophile?
The positively charged bromine atom acts as an electrophile, reacting with the double carbon bond. A pair of electrons from the carbon double bond move onto the positive bromine atom. The negatively charged bromide ion is acting as a nucleophile.
Is NH4+ an electrophile?
structure of the ammonium ion (NH4+). In an ammonium ion, nitrogen is bonded to hydrogen atoms and shares electrons with them. This causes all the orbitals to be fully filled and hence, nitrogen does not have space for any additional electrons. Thus, the ammonium ion is not an electrophile.
What are electrophilic and nucleophilic?
Electrophiles are those reactants that are either positively charged or neutral with no lone pair of electrons. A nucleophile is that chemical species that has negative charge or that has lone pairs of electrons. Lone pair of electrons is those electrons that do not get used in the bond.
Is nh4+ A nucleophile?
It is not nucleophile because it cannot donate the other pair of electron on oxygen since Oxygen has positive charge and it will be reluctant with its electronegativity. Positive charge is on oxygen and its octet is filled therefore its not an electrophile.
Can PH3 be a nucleophile?
PH3 acts as a nucleophile. Lone election pair on large sized Phosphorus (P) can be easily donated to an electron deficient end of an organic molecule and thus acts as a nuclephile.
