Question:
Sucrose when boiled with dilute HCl gives two functional isomers X and Y. X gives monocarboxylic acid with bromine water but not Y. The number of --OH groups in cyclic structure of X is
Sucrose when boiled with dilute HCl gives two functional isomers X and Y. X gives monocarboxylic acid with bromine water but not Y. The number of --OH groups in cyclic structure of X is
Show Hint
Glucose in cyclic form has 5 --OH groups; the aldehyde group gets oxidized in reactions with bromine water.

The Correct Option is C
Solution and Explanation
Sucrose hydrolyzes to glucose and fructose. Glucose, being an aldose, reacts with bromine water. In its cyclic structure (pyranose form), glucose contains five hydroxyl (--OH) groups.

- Ribose and 2-deoxyribose have an important role in biology. Among the most important derivatives are those with phosphate groups attached at the 5 position. Mono-, di- and tri-phosphate forms are important, as well as 3-5 cyclic monophosphates. Purines and pyrimidines form an important class of compounds with ribose and deoxyribose. When these purine and pyrimidine derivatives are coupled to a ribose sugar, they are called nucleosides.
