(a)
Interpretation:
The structural formula of reaction products in saponification using sodium hydroxide for the given ester has to be written.
Concept Introduction:
Breaking of the carbon‑oxygen single bond present between the “acid part” and “alcohol part” is one of the important reactions of ester. This process of breaking the bond between the carbon‑oxygen is known as ester hydrolysis or saponification. The condition prevails in the reaction determines it as ester hydrolysis of saponification.
Ester hydrolysis takes place in ester when it is treated with strong acid or enzymes as catalyst. Reverse of esterification reaction is the ester hydrolysis.
Saponification is the reaction that ester undergoes when a strong base is used to give the product as

Gentiobiose exists in two different forms, one melting at 86°C and the other at 190°C. The lower melting form is dextrorotatory ([α] 16°), the higher melting one is levorotatory ([α] -6°). The rotation of an aqueous solution of either form, however, gradually changes until a final value of [α] 9.6° is observed. Hydrolysis of gentiobiose is efficiently catalyzed by emulsin and produces two moles of D-glucose per mole of gentiobiose. Gentiobiose forms an octamethylether, which on hydrolysis in dilute acid yields 2,3,4,6-tetra-O-methyl-D-glucose and 2,3,4-tri-O-methyl-D-glucose. What is the structure of gentiobiose?
