Zoapatanol is found in the leaves of Montanoa tomentosa, a flowering plant native to Mexico. Classify the highlighted carbons in zoapatanol that are bonded to - OH groups as primary, secondary, tertiary, or quaternary. HO pod D Carbon highlighted in red: (Choose one) ▼ Carbon highlighted in blue: (Choose one) X OH

Cyclopentadienyl anion (shown) has the following characteristic. O it is an anion with six π electrons, meeting the Hückel rule for aromaticity O it is not aromatic because it has only four electrons and the tetrahedral carbon prevents cyclic conjugation O it is an anion with six electrons, meeting the Hückel rule for anti-aromaticity O it is an anion with four electrons, meeting the Hückel rule for aromaticity

Line structure Highest energy conformation of (R)-3-methylhexane (along C3-C4 bond) of (R)-3-methylhexane

Part C. The constitution of ectocarpene a volatile, sperm-cell-attracting material released by the eggs of the seaweed Ectocarpus siliculosus is shown below. In ectocarpene, all of the C-C double bonds have cis geometric configurations and the chirality center has an (S) absolute con- figuration. Please draw a spatially accurate structural representation of ectocarpene. Condensed Formula CH3CH₂CH=CH-CHCH=CHCH₂CH=CHCH2 Structural Formula
