Wrote this song for my extra credit in Organic Chemistry. Enjoy! :D 
Here are the lyrics: 

Substitution and Elimination reactions 
Oh, it’s quite hard to understand these mechanisms 

So here is a song for you to understand 
what the h*ck is going on 

Nucleophilic Substitution reactions exchanges the functional groups 
Sn2 and Sn1

Elimination reactions eliminates a functional group, and creates a carbon double bond, E1 and E2 

Sn2 and E2 has only one step the Leaving group leaves and 
The nucleophile attacks all at the same time 

Sn1 and E1 has two steps the leaving group leaves first and 
Then the nucleophile attacks 

But how do we know which reaction to use? It’s quite simple. 

Nucleophile reagents prefers the substitution reaction 
A base reagents prefers elimination reaction

When we’ve only got a nucleophile reagent the primary substrate will be Sn2 
Secondary substrate Sn2 + Sn1 unless we’ve got a solvent 
Tertiary substrate Sn1, never Sn2 

When we’ve only got a base reagent they’re all gonna be the E2 mechanism 

But when you’ve got both a strong nucleophile and base 
Then the primary substrate E2 minor Sn2 Major 
The secondary E2 major and Sn2 minor and tertiary E2
Because Sn2 is too sterically hindered 

When you’ve got both a weak nucleophile and base 
then the primary is Sn2 and E2, but it’s not practical 

Secondary substrate all the mechanisms will occur, 
unless you’ve got a secondary alcohol then an E1 reaction will occur 
with sulfuric acid and heat. 

Tertiary substrate Sn1 and E1 will occur. 

This was my substitution and elimination reaction song. 
Sn1, Sn2, e2 and E1. 

Very interesting concepts. 
I hope you understand them now.  


Substitution & Elimination Reactions

This is for an o-chem project! I hope you enjoy it :D 

Here's the lyrics: 
Aromaticity put into simplicity 
Pi bonds all lie within cyclic structures,
P orbitals are planar, overlapping
Find aromaticity with Hückel’s Rule,
4n+2 is equal to the pi electrons 

Toulene has methyl 
Phenol with alcohol
Anisole OCH3
Aniline NH2
These are the few benzenes that you should know

Aromaticity~~

Aromaticity into simplicity extra stability 
Favored over equilibrium and other molecules 
Discover conjugation to pass the evaluation 
Of an aromatic compound 

Toulene has methyl 
Phenol with alcohol
Anisole OCH3
Aniline NH2 
These are the few benzenes that you should know
