Glucose
Question

Statement-I: α-D(+) -glucopyranose and β-D(+)-glucopyranose are enantiomers.

Statement-II: Melting point of β-D(+)-glucopyranose is higher than that of  α-D(+) -glucopyranose.

Moderate
Solution

α-D-glucose and β-D-glucose differ in their configuration only at C-1 (or) functional group carbon (anomeric carbon). They are anomers (or) diastereomers (or) C-1 epimers.

They are not enantiomers. 

Melting point of α-D-glucose pyranose -419 K.

Melting point of β-D-glucose pyranose -423 K.
