Options:
  • A Glucose pentaacetate [structure A] doesn’t have a free —OH group at C1and so can’t be converted to the open chain form to give —CHO group and hence doesn’t form the oxime.
  • B Glucose pentaacetate is a cyclic compound, and oxime formation occurs primarily in linear molecules.
  • C Glucose pentaacetate is too large to participate in oxime reactions.
  • D Glucose pentaacetate is highly stable and does not readily undergo chemical reactions.
