| | Description | Designed for general chemistry courses that consider a lot of organic examples, or for students who plan to continue in organic chemistry. The Prentice Hall molecular model set can be used to construct realistic "scale models" illustrating the molecular structures of many thousands of compounds. With it one can build molecular models of representative compounds from virtually all classes of organic and inorganic compounds, including hydrocarbons, alcohols, carbonyls, thiols, sulfonic acids, phosphates, boranes, Grignard reagents, and many more. | |

 An excellent starter kit ... Dec 05, 2008
By M. Karr
Since the cover is difficult to decypher, the General and Organic molecular model set contains:
28 White(H) one-hole
14 Black(C) four-hole [tetrahedral]
8 Red(O) two-hole [angular]
4 Blue(N) four-hole [tetrahedral]
8 Green(Cl/F) one-hole
2 Orange(Br) one-hole
2 Yellow(S/metal) four-hole [tetrahedral]
2 Purple(P/I) four-hole [tetrahedral]
2 Brown(B/metal) five-hole [trigonal bipyramidal]
2 Silver(metal) six-hole [octahedral]
40 Single Bond (space-fill)
40 Single Bond (Ball/Stick)
12 Double/Triple Bond
4 S=O P=O Double Bond/lone pairs
although mine came with a few extra of the bonds (unless I miscounted)
Tool for prying apart space-fill models and a booklet which contains helpful pointers for constructing angular, tetrahedral, trigonal bipyramidal, octahedral, linear, trigonal pyramidal, trigonal planar, square planar, and other molecular geometries.
Different sizes of the atoms are close to scale at:
Space-fill: approx. 1.7cm/100pm
Ball/Stick: approx. 2.8cm/100pm
I bought two sets and mixed them together to make up for the lack of Carbon and Nitrogen, at least now I can experiment with nucleotides! :)
The downside (if it is a downside) to this kit is the difficulty of snapping together the bonds. At first some of the bonds are EXTREMELY hard to snap in, but after working with this set for a while they "loosen" up a bit. The advantage to this is that I've actually accidentally dropped a molecule and cringed thinking about trying to find all those atoms after impact ... but it held together! Not a single atom came loose, not even a Hydrogen! I've had kits in the past where part of the molecule falls apart while you're working on the other side, but not with this set. Your molecules stay together until you decide to take them apart! :) A few tips on using the space-fill bond separator tool would have been helpful, but it's fairly easy to figure out - it gets easier and easier to use. My fingers were sure sore after the first day! LOL
The booklet that's included is VERY helpful. It's set up like a tutorial, which even gives you pointers about analysis of molecular geometries - how to estimate relative boiling points, relative stability of isomers, etc; and it's short enough that it keeps your attention. A well-thought-out guide.
All in all I'm extremely impressed and satisfied with this set. I wish they had larger supplemental sets so you could expand, buying 100 extra Hydrogens, 50 extra Nitrogens and Carbons. Then I could make a whole twist of DNA . . . Sigh (Cat toys for nerds, indeed!!!).

 There is nothing like seeing it in 3-D. Apr 01, 2000
By Jessica McGoran
This model set was so very helpful during my study of organic Chemistry! I loved being able to see the carbon chains and manipulate them. It is so easy to name the molecule when you can see it in 3-D. Much better than trying to write them on paper, especially the benzene rings, and the double and triple bonds. The kit is almost a requirement for anyone trying to name isomers. The kit makes it so easy to tell that isopropylpentane and 3ethyl-2methyl-pentane are the same structure. This is a wonderful tool for anyone studying organic chemistry. The book which comes with the kit gives you plenty of information to get you started. A must have!

Useful for Organic, Inorganic, and Gen Chem Aug 27, 2001
Very easy to use. As a chem major, who has trouble visualizing in three dimensions this kit was invaluable. I used it in organic class for enantimers and conformational analysis. In p-chem it was helpful for group theory. In inorganic chem, I used it again for group theory and for visualizing inorganic molecules. Much more versitile than the simple organic modeling kits

Superior set, a must have for Orgo, and should have for General Chem Nov 16, 2005
By Microbiologist, RN, and perpetual student.
"~BB"
This is a good set to have for any Chemistry student. For College Freshman Chemistry I and II, this helps when you get to orbitals and their geometrical shapes... rather than just memorizing that an sp3 carbon is tetrahedral, or that an sp2 carbon is planar, you can 'see' it! This helps a bunch and brings some meaning to otherwise meaningless technical jargon.
Also, having gone to a couple of colleges, and visited even more, this type of set is the preferred set among instructors, and I can see why.
This set allows for both ball and stick and space-filling models. I have no complaints...
Though, just 1 set seems to be a little stingy on what they give... I just bought two and mixed them.
A must have. A+

Great! Oct 10, 2007
By J. Mirabal
Excellent quality, very useful for general, organic and inorganic chemistry. The only problem is that there are not a lot of atoms to build large molecules like sucrose, but for it is great for visualizing things like the chair conformation of cyclohexane.
