Answer» Solution :(a) (i) Acetylation of glucose with acetic anhydride gives glucose pentaacetate which confirms the presence of five OH groups. or Glucose + Acetic anhydride `rarr` Penta-acetyl glucose (ii) When glucose heated with HI, it forms n-hexane, SUGGESTING that all six carbon atoms are LINKED in a straight chain. or Glucose + HI/red `P rarr n`-Hexane (b) Denaturatio is loss biological activity of a protein. Or Secondary and tertiary structure of protein is DESTROYED due to heating and pH change. Eg : The COAGULATION egg on heating, curdling of milk by BACTERIA. (c ) `beta-D-2` deoxyribose OR deoxyribose |
