Organic molecule formulas

Hi,

Does anyone know if we supposed to memorize all the general molecular formulas between alkanes, alkenes, alkynes, and all the cyclo structures?
Thanks in advance.

I don't know if we necessarily have to memorize the general formulas, but it might help to be familiar for them.
For instance, alkanes have the form (C2nH2n+2)
Alkenes (C2nH2n)
Alkynes (C2nH2n-2)
I find that it is also helpful to draw out the structures if you are unsure and count the number of molecules there should be in order for carbon to have 4 bonds.
Hope this helps!

I think it's pretty important to know the formulas and how to name the longest carbon chain based on that.
