Identify strongest conjugate base among the following:
Correct answer: A. OH-
- A. OH-
- B. RCOO-
- C. OR-
- D. PhO-
Explanation
The strength of a conjugate base is inversely proportional to the strength of its parent acid. Alcohols (ROH) are extremely weak acids (weaker than water), which means their conjugate bases. alkoxides (RO). are very strong bases. Note: OH- is also very strong, but alkoxides are generally stronger.

About Carboxylic Acids
Carboxylic acids are named and studied through the combined effects of the carbonyl and hydroxyl groups, their preparation, acidity and hydrogen bonding. Reactions include neutralisation, esterification, reduction and conversion into acid chlorides, anhydrides, esters and amides, with emphasis on how these derivatives interconvert.
