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)

Genral formula of diketo and dialdehyde is ${\text{C}}_{\text{n}}{\text{H}}_{\text{2n}-2}{\text{O}}_2$ and general formula of diol is ${\text{C}}_{\text{n}}{\text{H}}_{3\text{n}}{\text{O}}_2$

Open chain carboxylic acid having $C_n{H}_{2n}{O}_2$ formula.
