Question

Ionic species are stabilised by the dispersal of charge. Which of the following carboxylate ion is the most stable?
A. `CH_(3)-overset(O)overset(||)(C)-O^(-)`
B. `Cl-CH_(2)-overset(O)overset(||)(C)-O^(-)`
C. `F-CH_(2)-overset(O)overset(||)(C)-O^(-)`
D.

Answer 1

Correct Answer - D

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.
