Interpretation Introduction

(a)

Interpretation: The glycosides formed by the treatment of $\text{β}$-D-mannose with ${\text{CH}}_{\text{3}}{\text{CH}}_{\text{2}}\text{OH}$, $\text{HCl}$ are to be predicted.

Concept introduction: The characteristic bond of glycoside is $-\text{O}-$. A hemiacetal converts into acetal when a monosaccharide is treated with alcohol and $\text{HCl}$. The acetal formed is known as glycoside. The hydrolysis of glycoside generates two compounds that have $\text{OH}$ group.

Interpretation Introduction

(b)

Interpretation: The glycosides formed by the treatment of $\text{α}$-D-gluose with ${\text{CH}}_{\text{3}}{\text{CH}}_{\text{2}}\text{OH}$, $\text{HCl}$ are to be predicted.

Interpretation Introduction

(c)

Interpretation: The glycosides formed by the treatment of $\text{β}$-D-fructose with ${\text{CH}}_{\text{3}}{\text{CH}}_{\text{2}}\text{OH}$, $\text{HCl}$ are to be predicted.
