Not a big deal for most applications, but what you are calling grey tetrahedrons are actually sp2 centers. These have 120 bond angles instead of the sp3 black 109.5 bond angles. Use them with the grey double bonds to get 120 bond angles.
You are right-however, I find that getting an sp2 center is no big deal-however, in some of the stereochemistry problems-having ability to access different colored Td are more useful, especially to beginning students.
True, but you could use any of the other colors- I think the different colored Td centers will be a bit more useful than different colored sp2 centers-those are relatively easy to identify in a molecule. The different colored Td centers help a student visualize atoms other than carbon with non-bonding electrons- say a structure with both Td N and O-atoms.
this kit single handedly carried my chem grade !!!!!
thank you! i couldnt get them to click for the longest time :)
