I don't even study chemistry too. Is chemistry really this easy?

you just have to count man.

neat drawings

Whats a brainlet like you doing on sci, OP?

Yes, chemistry is nothing but drawing wacky hexagons and then counting the atoms. Please don't tell anyone or we'll lose our funding.

You can determine it abstractly too. Consider an unbranched acyclic alkane. Each carbon forms four bonds, three of which are to hydrogen at the ends, and two elsewhere. So this alkane will have 2 (n-2)+2*3=2n+2 hydrogens, where n is the number of carbons, for n>1. Now, clearly branching preserves this quantity, as it gives a constitutional isomer, but rings and multiple bonding both involve replacing two C-H bonds with one C-C bond, and each instance of one decreases the number of hydrogens by 2. The number of such features is referred to as the "degree of unsaturation"

Or you could, y'know, just look at the figure and see whether it's 4-3, 4-2, or whatever by counting the goddamn lines touching a carbon

Lol this is fucking babby tier
t. only took high school chemistry
