how do you explain the absence of aldehyde group in the pentaacetate of d-glucose?

In D-glucose pentaacetate, the aldehyde group is absent because glucose primarily exists in a cyclic hemiacetal form (not as an open-chain aldehyde). Acetylation esterifies all hydroxyl groups, including the anomeric -OH at C1. This locks the molecule in the cyclic form, preventing reversion to the open-chain aldehyde structure. The anomeric carbon becomes an ester, not an aldehyde. 

Aldehydes and Ketones: Functional Group Isomers via Carbonyl Position

This occurs when they share the same molecular formula but differ in the position of the carbonyl group (C=O):

1. Aldehydes have the carbonyl group at the end of the carbon chain (attached to at least one H atom).

2. Ketones have the carbonyl group in the middle of the carbon chain (attached to two carbon atoms).
