A) Lactose
B) Maltose
C) Sucrose
D) None of these
Correct Answer: B
Solution :
Key Idea: Write the hydrolysis reaction for all choices to find the answer: (i) \[\underset{sucrose}{\mathop{{{C}_{12}}{{H}_{22}}{{O}_{11}}}}\,+{{H}_{2}}O\xrightarrow{{}}\underset{glucose}{\mathop{{{C}_{6}}{{H}_{12}}{{O}_{6}}}}\,\]\[\underset{fructose}{\mathop{+{{C}_{6}}{{H}_{12}}{{O}_{6}}}}\,\] (ii) \[\underset{maltose}{\mathop{{{C}_{12}}{{H}_{22}}{{O}_{11}}}}\,+{{H}_{2}}O\xrightarrow{{}}\underset{glucose}{\mathop{2{{C}_{6}}{{H}_{12}}{{O}_{6}}}}\,\] (iii) \[\underset{lactose}{\mathop{{{C}_{12}}{{H}_{22}}{{O}_{11}}}}\,+{{H}_{2}}O\xrightarrow{{{H}^{+}}}\underset{glucose}{\mathop{2{{C}_{6}}{{H}_{12}}{{O}_{6}}}}\,\] \[\underset{galactose}{\mathop{+{{C}_{6}}{{H}_{12}}{{O}_{6}}}}\,\]You need to login to perform this action.
