|
|
Electrophiles are positively charged or neutral species having vacant orbitals
|
|
|
The electrophiles are attacked by the most electron-populated part of one nucleophile
|
|
|
Electrophiles are Lewis base
|
|
|
-NO2 and-CH3 are examples of electrophiles
|
Detailed explanation-1: -1. Which of the following statement is incorrect about electrophiles? Explanation: Because electrophiles accept electrons, they are Lewis acids not Lewis base, according to Acid-Base reaction theories.
Detailed explanation-2: -To avoid confusion between the Lewis and the Bronsted definitions of acids and bases, Lewis bases are sometimes called nucleophiles, and Lewis acids are called electrophiles. In the example above, water acts as a nucleophile (donates electrons), and the carbocation acts as an electrophile (receives electrons).
Detailed explanation-3: -Hence, we conclude that the correct statement regarding electrophile is that electrophile can be either neutral or positively charged species and can form a bond by accepting a pair of electrons from a nucleophile.
Detailed explanation-4: -Electrophiles mainly interact with nucleophiles through addition and substitution reactions in organic reactions. Because electrophiles accept electrons, they are Lewis acids essentially.
Detailed explanation-5: -Nucleophiles are not electron seeking.
