Alkenes such as ethylene (ethene) are important in both industrial & biological processes. Ethylene. for example, is both a common plant hormone that causes ripening & a precursor for making ethylene glycol (antifreeze) & polyester fibres.

The 68845NV student set can build a variety of simple linear alkenes including: ethene (C2H4), propene (C3H6), butene (C4H8), pentene (C5H10), hexene (C6H12), heptene (C7H14), octene (C8H16) up to nonene (C9H18) & their isomers. Longer alkenes of 9 to 20 carbons are listed below but require extra atoms to build them.

Alkenes with 2 double bonds are called dienes of which there are 3 types, cumulated, conjugated & isolated. These consist of 2 pairs of double bonded carbon atoms that are adjacent, separated by a single bond or by 2 single bonds are more. Examples of these are 2,3-pentadiene, 1,3 pentadiene & 1,4 pentadiene respectively.

Indigo Instruments has maintained a substantial inventory of genuine Cochranes of Oxford (Orbit) atoms & bonds for over 30+ years (scroll down to see "Skeletal (Orbit/Minit). These parts are compatible with every molecular model set we have sold since day 1. This level of quality may appear expensive but no parts support from other vendors costs even more.

Details
Simple alkenes shown in the image include ethene, propene & the isomers of butene. Double bonds are represented by the white 35mm flexible bonds; C-C with 30mm grey bonds; C-H with 20mm bonds.

Longer, straight chain alkenes with 9 to 20 carbons include: decene (C10H20), undecene (C11H22), dodecene (C12H24), tridecene (C13H26), tetradecene (C14H28), pentadecene (C15H30), hexadecene (C16H32, heptadecene (C17H34), octadecene (C18H36), nonadecene (C19H38). Enter these compounds into the Indigo® Instruments 3D Molecular Model Builder (use Orbit Basic Style) to determine how many extra bonds & atoms you will need to build them.

Bought two of these because I prefer them to the one used at the university. Easy to use and has a good flexibility.

I've had consistently great service from this company. Our students seem to really appreciate the reasonable price. In the years that we've used this product, not one has been returned due to defects.

Considering how many of these we sell to schools every year, that is high praise indeed. Thanks letting us know.
