During these last months ChemiProject have been proposed various exercises type test organic chemistry on the official Facebook. To find any synthesis or chemical reactivity or any of the functional groups that was wrong.
These exercises are based on real reactions and if you look at the literature, are drawn from scientific journals of high impact factor (very prestigious) like Angwewandte , JACS and Nature .
The exercises are separated into two categories, for fans of this educational game and for organic chemist. Logically, chemist or fans who have played, will have a capacity to respond correctly much higher than average, showing that the teaching strategies employed work.
Here we will explain and analyze each of the questions
For chemistry students and fans:
So here we have the typical question wherein you have to look in detail the cards to find the correct answer.
If you look, the only change in each options is the color of the ends of the cards. Remember that each color represents a functional group and those who have played ChemiProject chemicals do not become strangers.
In short, you have to select the correct functional groups. In this case, the chemical structure has an alkene and one halogen and we see at any time the group alcoholt , borate or amine.
Then, the correct answer is a)
2nd and 3rd Question
These two questions show the same. It is the '' Proof of concept '' of the game. You have too figure out that is the correct product of the reaction.
In the left figure we see how the first card can react with the second card (twice), they are the chemical reagents to form a product. They use two halogens of the first card and a borate from the second.
So, A tip, the final compound will not have borates and halogens!
And, the second track, the chemical formula of the final product will have to be similar to that of the reagents, once the first 1 and 2 times the second card.
That mean the correct answer is B.
On the question of the right we follow a similar strategy. The chemical must resemble the two reagents, losing or changing functional groups which have been combined cards. We can see that the ´´heart´´ has exactly the same chemical formula of the reactants, so it is not the final product. Moreover, the ´´smiling face´´ is longer, but not at all like the first reagent, in fact, is twice the second reagent, so the product can not be.
Therefore, the correct answer is the ´´like´´, since it has a part of the first and of the second card / chemical structure (of the two reagents), losing both the group acid and the alcohol group.
This already is a question for professional players who have understood the basics the game. The image shows a chemical addition reaction, wherein two different chemicals form a product. We need to figure out how tolink the cards. The chemical formula of the right is the combination of the two of the left. Each functional group has a representative color. In the card on the right (product) we can see how the blues groups (alkenes) are together, belonging one to the first card from the left, and the other from the second. That is, the correct answer is a).
We can see that the chemical reaction took place in 2018, and published in one of those prestigious scientific journals, JACS .
This is easy. The first card has has two halogen groups, two bromines and an alkene group. After performing the chemical reaction with an organilític compound ( organometallics are not explicitly in the game, even if you can make Suzuki or sonogahria reaccton) and catalyzed by an organometallic copper complex gives us a product that has lost the alkene . There is no error, the correct answer is C.
Questions for chemical / biochemical.
As we have said before, this game has limitations, and exercises chemical try to clarify this point. This game of science want to tell you the Weaks points, and wants to show it to the players/students.
Under the question you can read the game combines functional groups, and what the author wants is to discover (as a chemist) the wrong functional groups. The cards on the left and right has a carbamate no ketone and the middle one alkyne, no alkene. For that, if you're not a chemist you can´t know, but if you're a chemist or are in the process take care of this point. This point is specified in the instructions, in questions, Youtube videos and now here, CAREFUL with the name of funcionales.
As I said, the questions for chemist try to show inconsistencies on this educational game. In the game when we combine two cards, we say that the molecular weight is the sum of the previous two cards, but we know that is almost never the case. Usually a small part is gone. It would be very difficult to play with this in mind, so that point was abolished. This reaction is lost, for example, two hydrogen atoms. So the correct answer is C.
Paying attention to these two points, even chemists can learn something, especially the uses and generic names of chemical compounds. It may even be interesting to biologists, pharmacists and doctors.
To not end up talking about the mistakes of the game, here's a question of the real game, the BreakRules exposed. As I said, until the chemicals may not know it right answer. Only good chemist with good memory could know how many moles of H2O has one liter of water. Anyway I will not reveal. This is very simple for chemist as they can discover by doing simple math, so encouragement.
