Organic chemistry notes.. yes we are doing newman projections. Yes if you send me molecules in my askbox I will yap abt them

🗣:- Genie and Aladdin are THE best duo of all time!

Me- hold my arabic coffee, KiD~😏☕

YYYYEP~ This is my anthroponization of Iago...

AND GODDAM I DON'T REGRET ANYTHING>:}

Yes, I'm new here, so I'll have to explain: - I have a salivary race of monster-birds that can mimic people (actually, they feed on them 0_0🔪) and they have an intermediate form, actually here it is~

In modern times, they are called Reporters (because some pretend to be them)

In ancient times, they were called Alkanes.

And this is a very old art, when I realized that I really wanted to adjust MMYYY 💖🦜~SWEEEEET NASTYY DRAMA QUEEN PAAAARROT~🦜💖 to my inventions) Well... NOW I DRAW HIM LIKE THIS ALL THE TIME *🥁*

AND YEEEAH HE LOOKS LIKE A GYPSY

AANNDD YYYEEEEAAAAAHHH HE'S CHUBBY

...

Dude... Let me eat him I SO WANT HIM

!!!!!RRRRAAAAAAAA!!!!!!>:□

[ maybe I'll fully humanize him later, but WHO KNOWS)>;P ]

(Ps: aaand if you want, I can explain a little more about some of the details of this au, and there are sooo many of them👀 even in this art there are a lot of hidden details)

Alkanes: Crash Course Organic Chemistry #6:

Alkanes are kind of the wallflowers of organic chemistry, but they still have important functions in the world around us. In this episode of Crash Course Organic Chemistry we’re building our knowledge of organic molecules by learning all about these so called couch potatoes from how they are separated from crude oil to how to use Newman projections to predict torsional strain and steric hinderance. We’ll also learn the names of some common conformers and get an introduction to cycloalkanes.

naming alkanes.

Before proceeding on the steps on how to correctly name and identify alkanes, alkanes should be defined first. Alkanes are hydrocarbons which can only form a single bond unlike alkenes and alkynes which can form double and triple bonds respectively. The IUPAC Nomenclature are the guidelines that are needed to be followed in order to name the alkanes. Take note that the first ten alkanes should be memorized because most of them appear in different IUPAC names. The IUPAC system requires to have names for the unbranched chains and next will be the names for the attached simple alkyl groups. Alkyl groups are named by replacing the suffix "-ane" to "-yl".

Here are the most common alkyl groups:

                                                        source

And now, we can finally proceed to the IUPAC rules regarding alkane nomenclature. The process begins with:

1. Find the longest chain of the carbon atoms as this will give you the name of the parent chain.

Example:

In the figure below, the longest chain is six carbons therefore the parent chain is hexane.

2.  If two chains have the same number of carbons, choose the chain with the most substituents.

3. Number the carbons in the chain starting from the end nearest the first substituent.

Example:

In this structure, we will name the carbons from left to right because is it nearer to the first substituent.

4. If there are substituents that are the same number of carbons in from either end, start the numbering from the end nearest the next substituent

5. Multiplying prefixes are used when a substituent appears more than once. There are also no spaces in the final name.

Example:

There are three instances of the methyl substituent in this alkane therefore it will be called trimethyl.

6. Halogen substituents are given priority in naming

Now that the steps in naming were accomplished, the structure can be correctly named and it is the 2,3,4-trimethylhexane.

This week has been tough. I haven’t posted anything in a while because at the end of last week my school was hit with some really personal information and that last Thursday and Friday, everybody in school was emotionally exhausted, so it’s been tough. On Friday I did however leave school to attend the climate strike in my town and then I went to my boyfriend’s house because it was Valentines day. But to say I wasn’t hopeful at the start of this week to get loads of work done, would be a lie. I planned on doing a past paper for each of my subjects everyday - we were off for the week because it is mid-term - however, as per usual, I set up this workload thinking I’d actually be able to do it. I would love to say that I worked my ass off everyday this week, bu that would be the biggest load of bullshit ever; I didn’t properly start working till yesterday. I am proud of my chemistry notes I made yesterday, however, next week is our data tracking 3 (dt3) and on Monday I have biology...the one subject I’ve basically done nothing for. On Monday I have biology at 1:00, I have Tuesday off, Wednesday I have chemistry at 9:15, Thursday I have maths at 9:15 and finally on Friday I have physics at 9:15. I’m fucked. I don’t really know how to answer the questions from AS2 in biology and that whats most of the paper is going to be on. I also have physics homework but that won’t be due to till next week. On Wednesday afternoon my year has to go to this weird careers talk but I no longer have to go, but I already said I could, so next week is really not going to be a vibe. So I’m probably not going to post anything till next Saturday but I think that’s fair due to my exam timetable. Also not to flex but I’m proud of my chemistry mind-maps:
