Hello, my name is Andrey Yavkin, I’m in the 10th grade, I have a question about memorization in chemistry (organic and inorganic).
I have already effectively used mnemonics in almost the entire school subjects, but some things are given to me with great difficulty. I think this is a very important question for all schoolchildren who learn chemistry. My question is:
How to memorize in chemistry the properties of elements (what reacts with what and what substances are formed as a result), the properties of compounds (there are even more of them than there are elements). And most importantly, how to remember the reactions (because many of them are intuitively unpredictable and you just need to remember them), namely, what reacts with what and what substances are formed?
I want to be a doctor, but for this you need to know a lot of chemistry:) Biology is easy for me.
In chemistry, there are many individual properties of elements. For example, what reacts with what and what comes out of it. But there are so many of them that I need a special approach to memorize reactions and other properties, for example, as for numbers there is a system * PAO 00-99, I need the same system for chemistry. For example, I can easily remember (and understand) the reaction:
2Na + F2 = 2NaF, since I have an association for each of the elements and the Naf connection has its own association, but sometimes I come across examples that, when memorized by the same method, require a huge chain of mnemonics, where each sequence of associations is important, and which cannot be forgotten otherwise the reaction will be wrong.
3SnCl2 + 2Bi (NO3) 3 + 18 NaOH = 3Na2 [Sn (OH) 6] + 2Bi + 6NaCl + 6NaNO3
Let’s just try to memorize the reaction, for this we need to create about 25 images, but for a normal reaction, of which there are a lot in chemistry, this is inappropriate to do.
I want to concretize my question by giving one analogy. There is a special method in memorizing cards “shadow system”, where instead of 2700 pairs of cards, we create images for only 1350 pairs and place them in a special way so that the location method also tells us about the sequence of cards. I thought: "what if we create a technique approximately with the same memorization system, where instead of 17 images with correct encoding, we will need, for example, 3-5 images. And when I saw any C2H3NaO2, I didn’t have to create 4 images for elements and 3 images for numbers, and I I translated the compound immediately into my special PAO system in chemistry and enjoyed my life as a docktor
Do you have such a system for chemistry?
How would you memorize such equations?
In organic chemistry, there are long and very branched compounds. How can I remember where the chain is turning (left or right)? How many, for example, CH2 groups and in what order do they stand?
And the last question
How to memorize organic reactions, because there are many repetitive elements in them. Here’s an example:
Cl-CH2-COOH + 2NH3 = NH2-CH2-COOH + NH4Cl
I have an idea how to create such a system PAO, but it is not fully thought out. I am ready to listen to your ideas and additions. In my technique, I don’t know how to deal with the coefficients before compounds. And what to do with inorganic compounds.
Let’s take any element. S - sulfur. Now let’s take the numbers that most often will stand at the index of this element - 2,3,4. Number 2 is coded with the letter T, number 3 with the letter P. Thus, the connection of ST and SP, we will come up with a new word: STAR - S2 and SOAP- S3. Then we can create action and something else for this technique. And then we can do other things of the same kind.
