Molecular Visions (Organic, Inorganic, Organometallic) Molecular Model Kit #1 by Darling Models to accompany Organic Chemistry

This is a pretty fabulous set if you know what you are doing and what you want. I started in organic chemistry a few decades ago and moved on to pharmaceutical/medicinal chemistry in graduate school. Since then I have been in the business side of the industry but wanted to get back to molecules. I ordered two of these kits because I suspected one wouldn't be enough. Well, as a learning tool, one would be enough. With two kits I was able to build three interesting pharmaceutically active molecule models.These models are a bit tough to initially snap together, but once they are snapped together they are easy to reassemble into other molecules. These are great models and similar to other teaching/learning models i used in undergraduate/graduate school. Putting them together and then looking at the configuration of a molecule provides a completely different perspective to what is on a screen or on paper. These aren't Dreiding models but they cost tens, not thousands, of dollars.The set is quite generous in terms of what is supplied, perhaps too many oxygen and not enough nitrogen parts. That may be an issue of my preference for modeling alkaloids. But, the manual provides information on how to order additional parts online at what I consider to be very reasonable prices. They claim to ship internationally.The enclosed manual is an excellent introduction to molecular modeling and bond types. Overall I'm totally delighted by this molecular modeling kit, and I have worked with the very best. A very inexpensive investment if you are serious about organic chemistry or pharmaceutical chemistry. Seeing is the start of understanding.

Todos los modelos moleculares que conozco tienen ventajas y desventajas con respecto a otros. Algunos son muy útiles para exponer algunas cosas pero no son los mejores para otras. Estos modelos en particular me han resultado útiles como complemento a otros que ya tengo. No son lo ideal para un curso de Química Orgánica, que es mi tema, pero sí son útiles como complemento a otros que ya tengo. Los recomiendo principalmente para cursos de Química General y Química inorgánica.

The molecular model I got is of good quality and none of the pieces were missing or broken. I am a teacher and this kit helps me in conveying many complicated topics to my students easily. I was really interested to buy this model because of the flexibility of the bonds which is very essential in demonstrating the ring flip analysis of cyclohexane. Thank you.

Opened the box which was seemingly organized and as I was configuring how to use it, I realized there were pieces missing pieces replaced pieces I don't need. It's useless. I only have one carbon???Don't recommend buying this from this seller since their is a chance you'll have the same fate.
