2. The molecules shown below are four terpineol isomers. They are isolated from plants and have distinct aromas. For example, a -terpineol is a common perfume ingredient and smells similar to lilacs. Hol H-O- a-terpineol B-terpineol Y-terpineol 4-terpineol A) Draw a structural isomer of terpineol that meet the following criteria. You should draw one unique structure for each set. You must draw each molecule twice, once as a skeletal structure and once as a complete Lewis structure showing all atoms, bonds, and lone pairs of electrons. i. Does not have a ring. ii. Has an E alkene. iii. Has a secondary alcohol. iv. Does not contain an alcohol. B) Draw a complete Lewis structure of a-terpineol showing all bonds, atoms and lone pairs of electrons.
Pyrethrin II and pyrethrosin are two natural products isolated from plants of the chrysanthemum family. Pyrethrin II is a natural insecticide and is marketed as such. Q,)State the number of stereoisomers possible for each molecule.
Draw the most stable structure of cis-1-tbutyl-2-methylcyclohexane. Your structure should clearly distinguish between axial and equatorial positions.
Cyclohexane derivatives exist primarily in the most stable of the available chair conformations. Give the position, axial or equatorial, of each of the three groups shown when the ring is in the most stable chair conformation. If a group divides its time equally between axial and equatorial positions, indicate this with ax/eq. The table of "Axial Strain Energies for Monosubstituted Cyclohexanes" found in the "Strain Energy Increments" section of the Reference tool is useful for answering this question.

1,2,3,4,5,6-Hexachlorocyclohexane shows cis,trans isomerism. At one time, a crude mixture of these isomers was sold as an insecticide. The insecticidal properties of the mixture arise from one isomer, known as lindane, which is cis-1,2,4,5-trans- 3,6-hexachlorocyclohexane. Q.) Which of the alternative chair conformations of lindane is more stable? Explain.
