The formula of palmitic acid
Correct answer: C. C16H32COOH
- A. C15H31COOH
- B. C13H27COOH
- C. C16H32COOH
- D. C17H35COOH
Explanation
Palmitic acid is a saturated fatty acid with 16 carbon atoms. Its formula reflects this chain length and functional groups, accurately represented as:C₁₆: Representing the 16 carbon atoms in the main chain.H₃₂: Representing the 32 hydrogen atoms attached to the carbon chain (two per carbon, excluding the hydrogens bound to the two functional groups).COOH: Representing the carboxylic acid group (-COOH) at the end of the chain.Therefore, considering the total number of carbon and hydrogen atoms and the presence of the carboxylic acid group, (c) C₁₆H₃₂COOH emerges as the accurate formula for palmitic acid.

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.
