Interpretation:
The Haworth projections of α-D-mannopyranose and β-D-mannopyranose has to be drawn.
Concept Introduction:
The cyclic representation of monosaccharides is known as Haworth projection. The five membered ring is said to be Furanose and six membered ring is said to be Pyranose. The five or six membered cyclic hemiacetals which have planar structure will be lying perpendicular to the plane of the paper.
In monosaccharides, the alcohol and carbonyl groups both are present. The two groups react with each other to form cyclic hemiacetals.

Using radii from Resource section 1 (p.901) and Born-Lande equation, calculate the lattice energy for PbS, which crystallizes in the NaCl structure. Then, use the Born-Haber cycle to obtain the value of lattice energy for PbS. You will need the following data following data: AH Pb(g) = 196 kJ/mol; AHƒ PbS = −98 kJ/mol; electron affinities for S(g)→S¯(g) is -201 kJ/mol; S¯(g) (g) is 640kJ/mol. Ionization energies for Pb are listed in Resource section 2, p.903. Remember that enthalpies of formation are calculated beginning with the elements in their standard states (S8 for sulfur). The formation of S2, AHF: S2 (g) = 535 kJ/mol. Compare the two values, and explain the difference. (8 points)arrow_forward
