The correct statement(s) about the following sugars $X$ and $Y$ is (are)
The correct statement(s) about the following sugars $X$ and $Y$ is (are)
$X$ is a reducing sugar and $Y$ is a non-reducing sugar
$X$ is a non-reducing sugar and $Y$ is a reducing sugar
the glucosidic linkages in $X$ and $Y$ are $\alpha$ and $\beta$, respectively
the glucosidic linkages in $X$ and $Y$ are $\beta$ and $\alpha$, respectively
Solution
$X$ has acetal linkage and $Y$ has hemiacetal linkage. Carbohydrate with hemiacetal linkage are reducing sugars and carbohydrate with acetal linkage are non reducing sugars.
$X$ is $\alpha$ anomer and $Y$ is $\beta$-anomer of $D(+)$ glucose.
