Electrophiles and Nucleophiles are atoms, bonds, or (small or small parts of) compounds that are involved in chemical reactions.
Nucleophiles are "nucleus loving" which means that they want to give up electrons and gain a bond with another atom. These are usually negative or neutral compounds. (-OH base is a good example, the oxygen usually gives electrons)
Electrophiles are the opposite, they are "electron loving" which means that they gain electrons (from the nucleophile to form a new bond). (A carbon-carbon double bond or hydrogen molecule can act as an electrophile for example.)
An electrophile is a compound with a positive change or a partial positive charge that could share the electrons of another compound.
A nucleophile is a compound with a negative charge or a partial negative charge that can share its electrons with another compound.
electrophiles are the electron deficient species whereas nucleophiles are the electron rich specie .the other difference is that electrophiles are the electron loving species and nucleophile are electron hating.
depending upon the reaction conditions halogens act as electrophiles,nucleophiles and freeradicals
quick answer is that nucleophiles like positive areas of molecules and electrophiles like negative areas of a molecule. In methane (CH4) the hydrogen and carbon have similar electronegativities and therefore there are no real positive and negative centres. Hope this helps mate
1. Practice! 2. Focus on Lewis acids (electrophiles) and bases (nucleophiles), and how the electron pairs move around 3. Focus on the "tree and branches" - themes and patterns - instead of trying to memorize a million "leaves".
Alkanes are not very reactive because of the stability of their bonds. The carbon hydrogen bonds found in alkanes are virtually nonpolar. Also, carbon and hydrogen have no lone pairs of electrons. This means that they are not subject to attack by nucleophiles or electrophiles.

Alcohols are versatile in nature because it can react both as electrophiles and nucleophiles according to the cleavage of bonds between them(i.e. O-H or C-O bond).

Nucleophiles which can attack through two different sites are called ambident nucleophiles. For example, cyanide ion is a resonance hybrid for its structure. It can attack either through carbon to form cyanides or through N to form isocyanides or carbylamines.

Alkanes are not very reactive because of the stability of their bonds. The carbon hydrogen bonds found in alkanes are virtually nonpolar. Also, carbon and hydrogen have no lone pairs of electrons. This means that they are not subject to attack by nucleophiles or electrophiles.
Lewis acids help in the generation of electrophiles in Friedel Crafts reactions.
