Chapter 5 - Alkenes: Bonding, Nomenclature, and Properties

Small subunits

________ are bound together enzymatically via an iterative process in the construction of big molecules, and then changed by following precise enzyme- catalyzed reactions.

Proton transfers

________ are the only ones covered by the Brnsted- Lowry definitions.

essential oils

The terpenes you are most likely familiar with, at least by odor, are components of so- called ________ derived by steam distillation or ether extraction of various plant parts.

isoprene units

Head- to- tail bonds between ________ are far more abundant in nature than head- to- head or tail- to- tail connections.

double bond

The ________ in norbornene does not have a bridgehead carbon, whereas the ________ in the other picture has.

significant strain

Because the alkene can not be planar while the rest of the carbons in the bicyclic system span the rings, this double bond configuration causes ________.

Terpene research

________ reveals the incredible diversity that nature can create from a simple carbon skeleton.

chiral core

Even though it lacks a(n) ________, the trans isomer is chiral.

molecular logic

Terpenes also demonstrate a key feature of biological systems '________.

carbon atoms

The ________ in myrcene and geraniol are cross- linked to form cyclic structures in the last four terpenes of the image attached.

Essential oils

________ include the low- molecular- weight compounds that are responsible for the distinctive plant aromas.
