Identify correct conversion during acidic hydrolysis from the following : (A) starch gives galactose. (B) cane sugar gives equal amount of glucose and fructose. (C) milk sugar gives glucose and galactose. (D) amylopectin gives glucose and fructose. (E) amylose gives only glucose. Choose the correct answer from the options given below :

The general acid hydrolysis reaction of a glycosidic bond is given by $$ \text{R1-O-R2} + \text{H}_2\text{O} \xrightarrow{\text{H}^+} \text{R1-OH} + \text{R2-OH} $$.

Below we examine the hydrolysis products of each option.

Option (A): Starch, composed of amylose and amylopectin, yields only glucose upon acidic hydrolysis and is therefore incorrect.

Option (B): Cane sugar (sucrose) hydrolyzes to equal amounts of glucose and fructose.
$$ \text{sucrose} + \text{H}_2\text{O} \xrightarrow{\text{H}^+} \text{glucose} + \text{fructose} $$ This option is correct $$-(1)$$.

Option (C): Milk sugar (lactose) hydrolyzes to glucose and galactose.
$$ \text{lactose} + \text{H}_2\text{O} \xrightarrow{\text{H}^+} \text{glucose} + \text{galactose} $$ This option is correct $$-(2)$$.

Option (D): Amylopectin yields only glucose units upon hydrolysis and does not produce fructose, making it incorrect.

Option (E): Amylose hydrolyzes to glucose units only and is therefore correct.

Collecting the correct conversions gives Options (B), (C), and (E).

Final Answer: Option B
