Identify correct conversion during acidic hydrolysis from the...

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 :

Options

  1. A(A), (B) and (C) only
  2. B(B), (C) and (E) only
  3. C(C), (D) and (E) only
  4. D(B), (C) and (D) only

Correct answer

B. (B), (C) and (E) only

Step-by-step solution

(A)(\mathrm{A}) Starch →H+/H2O\xrightarrow{\mathrm{H}^{+} / \mathrm{H}_2 \mathrm{O}} Glucose (B) Cane sugar →H+/H2O\xrightarrow{\mathrm{H}^{+} / \mathrm{H}_2 \mathrm{O}} glucose + fructose (Sucrose) 50%50%50 \% \quad 50 \% (C) Milk sugar →H+/H2O\xrightarrow{\mathrm{H}^{+} / \mathrm{H}_2 \mathrm{O}} glucose + galactose (Lactose) (D) Amylopectin →H+/H2O\xrightarrow{\mathrm{H}^{+} / \mathrm{H}_2 \mathrm{O}} Glucose (E) Amylose →H+/H2O\xrightarrow{\mathrm{H}^{+} / \mathrm{H}_2 \mathrm{O}} Glucose So, correct options are B,C,and E only.
