Question

tell me any tricks to remember which one is nucleophile and which one is electrophile

Answer 1

Read it thoroughly until you remember it

Answer 2

phile means loving
so nucleophile means nucleus loving
since nucleus has proton and neutron so basically it is positive so the one which is nucleophile must have negative charge.

and

electrophile means electron loving since electron has a negative charge so any electrophile must have positive charge.


hope it helps you
