understunding Organic Chemistry Mechanism

 The Secret for understunding Organic Chemistry Mechanism

in this video we're gonna focus on the secret of organic ,chemistry​ ,mechanism​ , and what I actually mean by secret, it's not magic, cause there is now way to make it easier, and no way to make it faster, all what you have to do is to work on some of the basics that you need to understand before starting the organic chemistry journey. And don't wish the organic chemistry was easy, wish you're better, and that's my purpose in this video, is to make you better as much as possible.
So,Let's begin with the basic number one, the first basic is the atom.
what is an atom ? 
An atom simply is a nucleus positively charged surrounded with electrons negatively charged, briefly, we can simplify it like that, a positive charge, surrounded by negative charge, Like the sun surrounded by planets , for example, the electron when it turns around the nucleus, it's something like the earth when it turns around the sun, So the sun is like the positive charge, and the earth is like a negative charge, in other words, the sun is like the nucleus , and the earth is like the electron. 
So imagine if the atom lost its electron, Can you tell me what will happen ? what will happens simply is that our atom will be positively charged, cause all what we have here is a positive charge, but could you imagine if an atom had acquired an electron, what will happen ? so what will happen simply is that our atom will be negatively charged, and of course the question is why ? because we have right here two negative charge, and one positive charge, mathematically -2+1 = -1, and that's it. 
And now let's have a little fun playing with the charges , so Imagine this little boy playing with a ball and meeting a friend who does not have a ball, The result is that they will play. The same goes for an atom that has an electron, it will play with another atom that does not have an electron. 
Conclusion : 
charges of opposite sign attract each other 
charges of the same sign repel each other.
With this simple principle, we can understand what a chemical bond is, And what are its types ? 
Imagine two boys playing with a rope What are the possibilities? If both of them have a rope, they can link their strands with each other, and so the result is a strong bond, the same thing for the atom, who plays the role of the rope is the electron, and the one who plays the role of the boy is the nucleus, when each atom decides to link its electron with the other, it is The result is a covalent bond. On the other hand, imagine an atom that has an electron, and another without it. Here I am talking about a positively charged atom, and a negatively charged atom, what will happen? What will happen is that the positive charge will be attracted to the negative one, and this is how an ionic bond is formed. The question that we will ask is, what is the difference between an ionic bond and a covalent bond? The simple answer is that a covalent bond is between two boys of equal strength. Here it is necessary to talk about electronegativity, what is electronegativity ? 
is the tendency of an atom to attract shared electrons (or electron density) to itself.
For example, if we have sodium atom with chlorine, chlorine is more electronegative, so it has the biggest tendency to attract the shared electron to itself, right ? as a result chlorine will be negatively charged, and sodium will be positivily charged. 
Now you can ask what is the relationship between this information and the mechanism of a chemical reaction?
 The answer is quite simple: When you want to fixe a chemical reaction, and you have the reactants, you want to predict the product of the chemical reaction, lemme give you an example, you have ... 
So the first step we will be comparing their electro negativities, which is the most electronegative element? Sure, chlorine, as a result , the carbon will be positively charged, and chlorine will be negatively charged, here we have a negatively charged element, so we will link the negative with the positive here, and so we will form a new bond , and because of that sometimes building new relationships requires us to destroy the old ones , we must destroy this bond. And so on. Finally, the art of organic chemistry is the art of playing with positive and negative charges.
