CrackOChem_Alkanes - pt 23

In this video, we begin our transition from general chemistry into the exciting world of organic chemistry!

Below are some of the topics we will cover...

GENERAL FEATURES
-alkanes (vs. alkenes, alkynes)
-units of unsaturation
-the line-angle method of drawing compounds

3 TYPES OF ISOMERS
1. constitutional
2. conformational
-staggered (anti, gauche) vs. eclipsed
-torsional + steric strain
-newman projections
3. stereoisomers

RINGS
-planar vs. puckered
-torsional + steric + angle strain
-axial vs. equatorial
-how to draw rings

CHIRALITY
-enantiomers
-R & S nomenclature
-priority rules
-diastereomers

...

About The Tutor

Garrett is a Harvard graduate. While earning his doctorate from the Harvard School Of Dental Medicine, he was hired by the university to propose and develop educational videos to complement the curriculum. During this time he worked with instructors at the medical and dental school to produce video tutorials in the areas of neurobiology, cardiology, pharmacology, radiology and pre-clinical dental laboratory.

However, Garrett's love for tutoring and helping students be able to understand complex subjects in a simple manner began with organic chemistry. He was initially told by his family, friends and instructors that organic chemistry would be the worst class he would ever take in college. Fortunately, with a lot of sweat, a few tears, and plenty of dry erase markers, Garrett was able to "crack the code" behind organic chemistry. In the process, he discovered a technique to teach ochem in a logical, straight forward manner, and the "CrackOChem" project was born. He spent the next several years developing this technique and passing it on to others through university organic chemistry tutorials, a study club, and organic polymer research. He was later hired by the University of California, Irvine for a full time position teaching advanced tutorials in chemistry and biology, and was also responsible for the hiring, training, and managing of university tutors.

Garrett is currently in orthodontic residency, but continues to actively help students through tutoring and future editions of organic chemistry video tutorials.

Thx alot again... But plz tell me u have more videos that go into alkyl halides, sn1, e1 reactions and alkenes. I can't find them anywhere.

[CrackOChem]

@bsheikhpoor Hello! We have videos covering the entire year of organic chemistry. We would post the link for them here, but Youtube doesn't let us post website links in these comment boxes. So just search youtube for "crackochem nucleophilic substitutions", "crackochem eliminations", "crackochem alkenes", or you can also find all our videos on the crackochem website itself.

Like everyone else, THANKS! Got a question for you, have you heard of meso compounds?

[CrackOChem]

@tido05

You're welcome tido!

Regarding meso compounds, those are compounds that have multiple stereocenters, but are super-imposable. Because they can be superimposed, they are not considered chiral, and not optically active. If you're having trouble visualizing this, try to use your models to see how they can be superimposed. So be careful when looking at cpds w/ multiple stereocenters. Some can be superimposed, and some can't. Those that cant are "meso cpds".

Happy Studying!

one word to describe these videos Awesome!!!! Thanks again 'CrackOchem'

[kris12326]

Awesome videos!! Please post some more!!

[medic3271]

You are a credit to teaching. Probably the best instructor of a science course I have ever seen. If only every instructor could use your techniques. Just outstanding. Many, many Thanks.

[grayviper]

you my friend are awesome!! I've learned so much from you

[flarethereal015]

I watched your vids starting from isomers down to this one :-). Excellent
