Step-by-step solution

D-glucose

D-glucose is an isomer of glucose that is biologically active. It is the source of energy for many organisms, occurs from the plant as photosynthesis. Using certain reagents, d-glucose can be converted into a required compound.

Conversion of d-glucose into reactant a and b

(a) When d-glucose reacts with ${\mathrm{CH}}_3\mathrm{OH},\mathrm{HCl}$forms a compound which on further reaction with ${\mathrm{CH}}_3{\mathrm{CH}}_2\mathrm{I},{\mathrm{Ag}}_2\mathrm{O}$gives the following compound.

Conversion of d-glucose into a(b) When d-glucose reacts with ${\mathrm{NaBH}}_4,{\mathrm{CH}}_3\mathrm{OH}$ forms a compound which on further reaction with ${\mathrm{CH}}_3\mathrm{I},{\mathrm{Ag}}_2\mathrm{O}$gives the following compound.

Conversion of d-glucose into b

Conversion of d-glucose into reactant c

(c) When d-glucose reacts with ${\mathrm{Br}}_2,{\mathrm{H}}_2\mathrm{O}$ forms a compound which on further reaction with ${\mathrm{Ac}}_2\mathrm{O}$, pyridine gives the following compound.
