The monocarboxylic acids are monobasic acids. Which of the following is resonance hybrid structure of carboxylate ion?

Correct answer: C. Option C

  • A. Option A
  • B. Option B
  • C. Option C
  • D. Option D

Explanation

The carboxylate ion, which is the conjugate base of a carboxylic acid, can be represented by two resonance structures. The resonance hybrid structure is a combination of these two structures and is depicted as follows:O||C-O⁻The negative charge is delocalized over both oxygen atoms, leading to a more stable structure than either resonance contributor alone.

About Biological Molecules

The chapter covers water's polarity and biological roles, carbohydrates, lipids, proteins and nucleic acids, including their monomers, bonds, structures and functions. It also distinguishes RNA from DNA and explains conjugated molecules such as glycoproteins, glycolipids and nucleoproteins, which combine organic molecules with a non-protein component.
