You won't get very far in your study of organic chemistry without the periodic table of elements and an understanding of the common functional groups (or reactive centers) that dictate how most of a compound's chemical reactions occur.
Common functional groups in organic chemistry
In organic chemistry, functional groups (or reactive centers) are small structural units within molecules that dictate how most of the compound’s chemical reactions occur. Know these common functional groups you will run into in organic chemistry:
Periodic Table of Elements
Studying the elements of the periodic table is vital for understanding organic chemistry. So that you don’t have to memorize each element, they’re grouped together by their properties.
