Answer

(a.)and

(b.)and

Step by step solution

01

Anomers

Anomers are the cyclic saccharides which are epimers at the C1 (anomeric carbon).At C1, the伪 anomer has the OH group in the downside, and in the case of 尾anomer, the OH group is in the upside.

02

The structure of D-Arabinose

The D-Arabinose structure is shown as,

D-Arabinose structure

03

α and β anomers of D-arabinofuranose

In D-arabinofuranose, at C1, the 伪anomer has an OH group in the down position.

In the 尾anomer, the OH group is in the up position.

anomers of D-arabinofuranose

04

α and β anomers of D-arabinopyranose.

In D-arabinopyranose, at C1, the 伪anomer has an OH group downward.

In the尾anomer, the OH group is in the upward direction.
