Question

Eloctrophiles are electron .......... species.

Answer 1

Electrophiles are electron $\bold{\underline{loving}}$ species.


Their attraction for electrons is due to the presence of an electron - deficient atom in them.


They may be either positively charged or electrically neutral chemical species.


Electrophiles are electron - seeking.


They always attack the substrate molecule at the site of highest electron density.


They behave as Lewis Acid.


$(i) \ Positive \ electrophiles$ = $\sf{H^+, \ Cl^+, \ Br^+, \ I^+, \ etc.}$


$(ii) \ Neutral \ electrophiles$ = $\sf{SO_3, \ BF_3, \ AlCl_3, \ etc.}$
