Question

The general formula ${{C}_{n}}{{H}_{2n}}{{O}_{2}}$ could be for open chain

• A. diketones
• B. carboxylic acids
• C. diols
• D. dialdehydes

Answer 1

Answer: (B)

carboxylic acids

Answer 2

${{C}_{n}}{{H}_{2n}}{{O}_{2}}$ is the general formula for open chain carboxylic acid and ester, e.g., if $n=3\Rightarrow {{C}_{3}}{{H}_{6}}{{O}_{2}}$ Acid- $C{{H}_{3}}C{{H}_{2}}COOH$ Ester- $C{{H}_{3}}COOC{{H}_{3}}$
