Lowest boiling point is shown by:
Correct answer: B. Formic acid
- A. Acetic acid
- B. Formic acid
- C. Propionic acid
- D. Valeric acid
Explanation
The correct answer is B) Formic acid.The boiling points of carboxylic acids are relatively high due to intermolecular hydrogen bonding.Formic acid (HCOOH) has the lowest boiling point among the given options due to its smaller molecular size and weaker intermolecular forces compared to other carboxylic acids.HCOOH CH3COOH C2H5COOH100°C 118°C 141°C

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.
