Formaldehyde on condensation in the presence of calcium hydroxide: ______________?
Correct answer: A. Formose
- A. Formose
- B. Fructose
- C. Maltose
- D. Xylose
Explanation
In the presence of calcium hydroxide, formaldehyde molecules undergo condensation to form sugars, producing a mixture called formose. Fructose and xylose can occur among sugar products, but they are not the name of the overall condensation product. The likely wrong choice is fructose because formaldehyde condensation can produce higher sugars, including fructose-like products.

About Carboxylic Acid Derivatives
Carboxylic acid derivatives include acid halides, acid anhydrides, esters and amides, formed by replacing the hydroxyl group of a carboxylic acid. Their nomenclature, structures, preparation, hydrolysis and relative reactivity are linked through nucleophilic acyl substitution, which differs from the nucleophilic addition reactions of aldehydes and ketones.
