What are electrophiles and nucleophiles ? Give suitable examples for each.

Explanation

Electrophiles : Electrophiles are reagents that are attracted towards negative change or electron rich center they are either positively charged ions or electron deficient neutral molecular .
Example : ` CO_(2), AlCl_(3), BF_(3) , Fed_(3) NO^(+), NO_(2)^(-)`
Nucleophiles : Nucleophiles are reagents that has high affinity for electro-positive centers . They posses an atom has a unshared pair of electrons . They are usually negatively charged ions or electron rich neutral molecules,
Ex. ` NH_(3), R - NH_(2), R - SH, H_(2) O, R - OH `
