"Walk it Out 2"

Start at the chiral center
And walk out each bond
Ask Miss Chlorine her weight
But she don't tell
Cuz she the biggest one
She get the number one
Hydrogen's the smallest
He gets the number four

Two and three the same
What we gunna do?
Walk out another bond
So that we can choose
So throw your thumb up
Align with number four
Fingers curvin' toward
The biggest, number one

Now curl your fingers, son
Reach to two then three
If your rights curlin' up
Then R is what you'll see
If your lefts curlin' round
Then we'll call it S
Now you know why
Homies walk out bonds

We got a double bond
Substituents all differ
Cis and trans won't work
Use E Z nomenclature
First Doctor P. draws
A line of division
We look at each carbon
Find the biggest - crown the king

Don't get confused
This is what we mean
Walk out the sigma bonds
To the largest group you see
If they're on the same side
The name is zusammen
If they're on different sides
The name is entgegen

Were walking out bonds
All day and night
All this we must master
To get it right
Carbon is our friend
He should be yours too
Especially if you're taking
