⭐️Organic Chemistry - Carboxylic Acid ⭐️

 Tell me the structure of carboxylic acid.....

Is that acid or base?

Acid.

Do you know what is an acid? Of that carboxylic acid structure?

Not sure?

You have a double bond on the top, as =O

On the right side, you have a single bond of -OH

That is called alcohol structure.

Can you identify? 

So acid means what?

H+ in the solution.

The more H+ in the solution, the more concentration of H+ is present in the solution

They denote it as [ H+ ]

Correct?

So Carboxylic Acid is? Having a single bond H hanging there...

Do you want to take this question to your TA or professor, for preparing your general chemistry, reviewing the concentration of {H+]

Organic Chemsitry General Class vs. Honor Class

 You know when I tutor Organic chemistry, my background was honor class orgo.

Meaning, I never seeing the general organic chemistry textbook or notes from that professor's powerpoint slide.

We manually script all the orgo notes, and tests upon memory in drawing the mechanism a lot of times, or some kinds of....base on the notes that professor gives.

I am from SUNY Buffalo, General Orgo is 201/202, my class is 251/252

There is people who drop the class to go to those lower class orgo, was for the reason to taken PCAT or MCAT.

I didn't know that before, its like 16 years pass, and now I start to remember. 

Your gearing towards is your professional school.

So are you in the honor class Organic Chemistry like me?

I will tell you, when I tutor, I start to memorize all their reagents and reactants to products sheets too. But every university in America are all different.

If you look at all different university notes, I was very stressful when I create the Orgo YouTube channels to select questions to create a video. 

You have many variation.

As you approaching to know each class drawback, honor class has a lot of mechanism.

I will say, you learn mechanism so that some of the concepts you are strong by "moving the electron" more smooth, while you sketch your reaction diagram, in the orgo class.

That basic skill how to move the electron is the key.

As for the percentage of Orgo in PCAT, compare to the general chemistry, of course is so much less, so much less. Sometimes I will tell you, I am being so lazy, what if I prepare the section of the organic chemistry just never being examined at...I waste all the time not to study something else?

In my time of PCAT, I didn't really prepare though, I was a tutor in general chemistry.

I would encourage you, trying that with your school lab. No, those are not TA jobs.

Those are New York State funding down EOP, SSS, or ACE one of those minority program, or disadvantage of first generation students to go to school from their parents.

Organic Chemistry - Newman projection

 Do you really spend sometimes with the molecular kits?

Because in my time, when I was in the school, those things sometimes exist, sometimes just so don't, no one as if, really looking at those boxes we purchase, called 3D molecular kits.

Newman projection is where when you finish your carbon bones and bonds, no matter how you twist and turn....

I say it again, no matter how you twist and turn...unlike the Fischer projection, you destine to know what is a "backbone" this one definition means. if I have a molecular kit, its just 2 mins, to show you what Fischer project is telling you, and what Newman projection telling you.

Newman projtection telling you, you "rise up your hand with that things you deisgn"

Whatever you design

"pull up the distance of that molecule right in front of your eye."

How close?

One inche

Organic Chemistry - Fischer Projection

 Have you ever seen shrimps? From the middle their stomach....to see both side legs?

Well, when you have molecular kit, I will suggest you, taken to your TA offices.

Just say, I say about the shrimp. You have a backbone first......

Remember....what is the line for the backbone structure.

the backbone structure.

the backbone structure.

Organic Chemistry - Chiral definition

 Do you check your own textbook definition what is a chiral carbon means? 

Carbon can only bind to how many groups, if it is single bond? 4 

So if saying that is a chiral carbon, what does it means?

That carbon is binding to 4 different things. Under that observation, you cannot really say symmatry, so you say Chiral. Understand?

Mirror superimposible. 

You have to be clear, what you define in anatomy, that human is bilateral, symmetry beings, like cut in half, this half is the exact half than the other half.

That is not the case with the a Chiral Carbon doing a mirror image, of superimposible compounds.

Understand?

That is 4 different groups. Its wedge or hedge? meaning tilting out, that has a tail. That is not symmatry possible. Behind, behind...
