Bond Dissociation Energies and Yield

4. Use the bond dissociation energies (kcal/mole) listed below to predict which of the following statements 1 or 2) would be expected to yield the most product. Be sure to show your work.
R-H (98) R-C (81) RI (53) Cl-Cl (58) I-I (36)
H-Cl (103) H-I (71)

1) RH (g) + Cl 2 (g) - > RCL(g) + HCL (g)
2) RH (g) + I2 (g) -> RI (g) HI (g)

6.Draw the 3-dimensional structural formula for ® 2 -iodopentane. Use the wedge and dashed line convention.
7. b.Complete the table below based on what you know about enantiomers.

Property d-menthol l-menthol
Melting point 35 degrees C
Water solubility 1.4g/100mL
Density 0.90 g/mL
Rotation of plane
Polarized light +48 degrees
Rotation of plane
Polarized light of d,l mixture

c.Circle the chiral carbons in d- menthol. Assign absolute ( R vs S) configuration for each of the carbons you have circled.

Solution Summary

The yield of the organic products is determined by bond dissociation energies. Three dimensional structures for 2 -iodopentane is given. The enantiomers are given.
