Multiple Choice

$$\underset{(A)}{Maltose} \xrightarrow{MeOH / HCl} (B) \xrightarrow{Ac_2O / NaOAc} (C) \xrightarrow{H_3O^{\oplus}}(D)$$ Which statements are correct about the reaction of maltose?

AProduct $$(C)$$ is:
Correct Answer
BProduct $$(C)$$ is
CProduct $$(D)$$ are
DProducts $$(D)$$ are $$2$$mol $$\alpha$$- and $$\beta$$-D-glucose
Correct Answer

Solution

Maltose is $$D-glucopyranosyl$$ $$D-glucopyranose.$$
On treatment with methanol in the presence of $$HCl$$, the $$-OH$$ group of $$C1$$ carbon of glucose unit is methylated.
On treatment with acetic anhydride in the presence of sodium acetate, all the free $$-OH$$ groups are acetylated to form (C).
The resulting product on hydrolysis gives the products (D) which are $$2mol$$ - and $$-D-glucose.$$
