How do you explain the absence of aldehyde group in the pentaacetate of D
When glucose (α and β) is treated with acetic an- hydride, it forms a penta acetyl derivatives which does not contain a free hydroxyl (-OH) group at C -1, it cannot be hydrolysed in aqueous solution to give the open chain aldehyde group and hence glucose pentaacetate does not react with NH 2OH to form glucose oxime.
