1.	Ionic species are stabilised by the dispersal of charge. Which of the following carboxylate ion is the most stable?
Answer» `CH_(3)-overset(O)overset(\|\|)(C)-O^(-)` `Cl-CH_(2)-overset(O)overset(\|\|)(C)-O^(-)` `F-CH_(2)-overset(O)overset(\|\|)(C)-O^(-)` Solution : As F is most electronegative and in this structure there are TWO F atoms, therefore, DISPERSAL of negative CHARGE is maximum HENCE it is the most stable.
