Nucleophiles and electrophiles are reaction intermediates having electron rich and electron deficient centres respectively. Hence, they tend to attack electron deficient and electron rich centres respectively. Classify the following species as electrohiles and nuclephiles.

1.	Nucleophiles and electrophiles are reaction intermediates having electron rich and electron deficient centres respectively. Hence, they tend to attack electron deficient and electron rich centres respectively. Classify the following species as electrohiles and nuclephiles. (i) H_(3)CO^(-) (ii) H_(3)C-overset(O)overset(\|\|)(C)-O^(-) (iii) Cl (iv) Cl_(2)C: (v) (H_(3)C)_(3)C^(+) (vi) Br^(-) (vii) H_(3)COH (viii) R-NH-R
Answer» Solution :Electrophiles are electron seeking SPECIES or electron DEFICIENT species. These species may be neutral or POSITIVELY CHARGED. (iii) `overset(+)(Cl)` (iv) `Cl_(2)C:` (v) `(H_(3)C)_(3)C^(+)` are electrophiles. Nucleophiles are electron RICH species and may be neutrla or negatively charged. (i) `H_(3)CO^(-)` (ii) `CH_(3)COO^(-)` (iv) `Br^(-)` (vi) `CH_(3)OH` (viii) R-NH-R are nucleophiles.
