A) Maltose
B) Lactose
C) Amylose
D) Sucrose
Correct Answer: D
Solution :
On hydrolysis with dilute acids or in vertase or sucrase, sucrose gives an equimolar mixture of D- (+)-glucose and D-(-) -fructose. \[\underset{\left( bp\text{ }{{103}^{o}}C \right)}{\mathop{Pentan-1-al}}\,\] \[{{[a]}_{D}}=+{{66.5}^{o}}\]\[\underset{\begin{smallmatrix} D-\left( + \right)-glucose \\ {{[a]}_{D}}\text{ }=+{{52.7}^{o}} \end{smallmatrix}}{\mathop{{{C}_{6}}{{H}_{12}}{{O}_{6}}}}\,+\,\,\underset{\begin{smallmatrix} D-\left( - \right)-fmctose \\ [a]J)=-{{92.4}^{o}} \end{smallmatrix}}{\mathop{{{C}_{6}}{{H}_{12}}{{O}_{6}}}}\,\]
