Number of carbon atoms in valeric acid is:
Correct answer: B. 5
- A. 4
- B. 5
- C. 6
- D. 7
Explanation
Valeric acid is a carboxylic acid with the IUPAC name pentanoic acid. It consists of a straight chain of 5 carbon atoms (C5H10O2), which is why the correct answer is 5. The other options are incorrect because:4 carbon atoms would correspond to butanoic acid, which is different.6 carbon atoms would correspond to hexanoic acid, which also does not fit.7 carbon atoms would correspond to heptanoic acid, which is not valeric acid.Thus, the only valid option is 5, as it accurately reflects the number of carbon atoms in valeric 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.
