C)resonance effect of the carbonyl group
D)A and B
E)A and C
F)B and C
3

Which statement about the salt of a carboxylic acid is true?
A)it is the product of a neutralization reaction.
B)it will produce a carboxylate ion in solution.
C)the counter ion to the carboxylate ion is usually a group I or II metal.
D)the salt has an increased solubility in water compared to the acid.

B)the hydrogen and carbon atoms respectively.
C)the alkyl and carboxyl groups respectively.
D)the carboxyl and alkyl groups respectively.
E)the carboxylate and counter ion (the metal ion) respectively.
5

Which statement about halide substituents on a carboxylic acid is false?
