Question

What are electrophiles and give example of electrophilic substitution reaction?

Answer 1

electrophiles are electron loving spacies they have lack of electron.electron deficient compounds are electrophiles.These are positively charged

e.g. H+ BF3 Na+ etc

electrophilic substitution reactions are 1nitration 2sulphonation 3freidal craft reaction etc

I hope it's helpful to you please mark as brainly

Answer 2

Answer:

(1) The species which are electron seeking species i.e. electron deficient species are called electrophiles or electrophilic centre

(2) A polyatomic electrophile has an electron deficient atom in it called the electrophilic centre.

(3) They are positively charged species like H^+, NO^+_2, or neutral molecules with incomplete octet of electrons like BF_3, AICl_3, etc.
