Explore alkyne molecular models for teaching organic chemistry and biology. Learn about triple bonds, IUPAC naming, reactivity, and real-world uses in medicine and materials science.

Alkyne molecular models are essential for visualizing hydrocarbons with carbon–carbon triple bonds, a defining feature of this functional group. These models help students understand linear geometry, bond hybridization (sp), and the unique reactivity patterns that distinguish alkynes from alkenes and alkanes. By physically manipulating molecular models, learners can better grasp concepts such as naming according to IUPAC rules, functional group transformations, and the role of alkynes in synthetic chemistry, pharmaceutical design, and biochemical processes.

Indigo Instruments has held inventory of genuine Cochranes of Oxford (Orbit) atoms & bonds for 30+ years. These parts are compatible with every molecular model set we have sold since day 1. This quality may appear expensive but no parts support from other vendors costs even more.

Key Alkyne Functional Group Examples for the Classroom

 
Compound Chemistry Focus Biology / Medicine / Nursing Focus
Ethylene (ethyne) Basic alkyne structure, bond angles, sp hybridization. Found in trace amounts in metabolic processes.
Propyne Terminal alkyne acidity and reactivity with strong bases. Intermediate in synthesis of pharmaceutical compounds.
2-Butyne Internal alkyne structure, symmetry, and reduced acidity. Model for metabolic intermediates in synthetic drug pathways.
Phenylacetylene Aromatic–alkyne conjugation effects and electrophilic substitution. Structural motif in some bioactive molecules.
 

The image shows ethyne, propyne and the two isomers of butyne. Triple bonds are shown using the 50mm white flexible bonds. Single covalent carbon-carbon bonds are shown with 30mm grey bonds and carbon-hydrogen with 20mm. Build these & other alkynes with the Indigo® Instruments 3D Molecular Model Builder

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.
