Q

The correct statement regarding electrophile is :

• Option 1)

Electrophile is a negatively charged species and can form a bond by accepting a pair of electrons from a nucleophile

• Option 2)

Electrophile is a negatively charged species and can form a bond by accepting a pair of electrons from another electrophile

• Option 3)

Electrophiles are generally neutral species and can form a bond by accepting a pair of electrons from a nucleophile

• Option 4)

Electrophile can be either neutral or positively charged species and can form a bond by accepting a pair of electrons from a nucleophile

As we learnt in

Positively charged electrophiles -

Chemical species having capacity to attack e- rich portion of substance.

- wherein

$H^{+},Cl^{+},Br^{+},NO^{+},NO_{2}^{+},R^{+},$

and

Neutral electrophile -

Those netural chemical species having capacity to attack e-rich portion of substrate.

- wherein

$BF_{3},AlCl_{3},FeCl_{3},SO_{3},:CH_{2},:CCl_{2},\: R:N$

Electrophiles are those having the capacity to accept an electron from nucleophiles.

Option 1)

Electrophile is a negatively charged species and can form a bond by accepting a pair of electrons from a nucleophile

This option is incorrect.

Option 2)

Electrophile is a negatively charged species and can form a bond by accepting a pair of electrons from another electrophile

This option is incorrect.

Option 3)

Electrophiles are generally neutral species and can form a bond by accepting a pair of electrons from a nucleophile

This option is incorrect.

Option 4)

Electrophile can be either neutral or positively charged species and can form a bond by accepting a pair of electrons from a nucleophile

This option is correct.
